This grant in the Organic and Macromolecular Chemistry Program                  will support research by Prof. Jack Saltiel, which is concerned                 with determining the mechanisms, or step-by-step details, of                    selected chemical reactions caused by the absorption of light.                  A detailed understanding of such relatively simple reactions is                 an essential step toward the elucidation of complex                             light-initiated processes such as the vision sequence or the in                 vivo chemistry of Vitamin D.  This work continues research                      heretofore supported by Foundation grant CHE-8400706.                                                                                                           Specific research projects in Dr. Saltiel's program are divided                 into two areas.  The first topic of study concerns alkene                       photoisomerization, and the second concerns electrocyclic                       reactions of arenes.  Within the former are included                            investigations of (a) ground-state conformational control of                    the photophysics and photochemistry of arylethenes, including                   the analysis of conformationally rigid analogues; (b) the                       photochemical formation of trans-cyclohexenes and their                         chemistry; and (c) the mechanism of nonvertical triplet and                     singlet energy transfer, and the shape of stilbene's lowest                     triplet and lowest singlet potential energy surfaces.  The                      interest in ground-state conformational control has been                        heightened by successful application of principal component                     analysis to the resolution of complex experimental spectra into                 the contributions from individual conformers.  The second area                  of study has as its major theme the role of triplet-triplet                     annihilation as a pathway to arene photochemistry.                              Spectroscopic observations on transient intermediates will                      provide rate constants for the interpretation of steady-state                   data.
