The I-APS Award in Photochemistry was established in 1988 to recognize outstanding contributions by members of the Society to the advancement of the photochemical and photophysical sciences. The award recognizes achievements made during the past ten years of the nominee's career. The winner will present an award lecture at the upcoming Winter Conference and will be reimbursed for travel expenses associated with attending the conference.

Nominations consist of a detailed statement of the nominee's scientific achievements during the last ten years, a curriculum vitae and publications list. Seconding letters from colleagues familiar with the nominee's work are also helpful to the committee.

The I-APS Young Investigator Award was established in 2002 to recognize outstanding photoscientific contributions by Society members who have held an independent research position for no more than five years at the time of application. The winner will present an award lecture at the upcoming Winter Conference and will receive up to $1000 to cover travel expenses associated with attending the conference.

Applications or nominations consist of a statement of independent research accomplishments, a curriculum vitae that includes the date of appointment to an independent research position and lists of publications, funding, and awards, and two letters of recommendation sent directly to the Chair of the I-APS Awards Committee.

In recognition of his central role in the development of the modern photochemical sciences, the George S. Hammond Award is given for lifelong achievement in, and contributions to, the photochemical sciences. The Award is given biennially at an I-APS meeting in years that alternate with conferral of the Porter Medal, beginning in 2013. The Award has been endowed by generous contributions from Prof. Hammond’s former students and colleagues and will be administered by I-APS, but the awardee need not be a member of I-APS. Former Porter Medalists and I-APS Award winners are eligible.

The Nicholas J. Turro Award was established in 2017 through the generous contributions of his students and colleagues and recognizes innovative contributions in photochemical sciences that transformed thinking or led to substantial development of the field. The awardees are expected to have made sustained scientific contributions over a period of at least twenty years preceding the year of nomination as well as have demonstrated successful mentoring of the next generation of photochemists. The Turro Award will be given in alternate years with the George S. Hammond Award.

The nomination should include a detailed statement of the individual's achievements in research and mentoring, two letters of support, and the candidate's curriculum vitae. The nomination and letters of support should be from three different institutions. Individuals who are not members of I-APS, international nominees, and those who have not received another I-APS award within ten years of the nomination are eligible.

Professor Gerhard L. Closs was one of the outstanding chemists of the past century, receiving the 1991 A. C. Cope Award in chemistry from the American Chemical Society and the 1992 Award in Photochemistry from the Inter-American Photochemical Society. In addition to his contributions in photochemistry and other areas of chemistry, his contributions to the intellectual and social life of the chemical community are also fondly remembered. Professor Closs was a devoted teacher and mentor, and it is in remembrance of that spirit that the Inter-American Photochemical Society solicits contributions from graduate and undergraduate students for oral presentation at the I-APS Winter Conference on any subject involving photochemistry. The winner will receive travel expenses (up to $500) to attend the meeting and present his/her paper.

Applications for the Gerhard Closs Award consist of a one page abstract for his/her paper, curriculum vitae, and a letter of recommendation from his/her research advisor.

The G. Cilento Award was established in 1999 to facilitate attendance at I-APS Conferences by scientists and students working in Latin America, of age 35 or younger. The award provides up to $2000 USD and waiver of the conference registration fee. The awardee will present a short talk at the I-APS Conference.

Applications or nominations for the Cilento Award consist of a curriculum vitae, abstract of the proposed talk, indication of fluency in English, and a letter of recommendation from the research advisor if the applicant/nominee is a graduate or postdoctoral student.

The Society established the honor of Fellowship in 1993. Fellowship recognizes outstanding lifetime scientific achievements in photochemistry or contributions to either the science of photochemistry as a discipline or the furtherance of the society through service. Fellowship is limited to 4% of the membership of the Society and no more than two Fellows can be elected in a given year. Fellows may be requested to make a short presentation at the next Winter Conference and will receive a waiver of membership dues.

Nominations consist of statement describing the merit of the contribution to be recognized and should state clearly whether the award is for scientific or service contributions. Seconding letters are not required, but may be submitted. Nominees should be members of the Society. Exceptions to this requirement require special justification by the nominator.
