The lowest singlet state of purine


, : The lowest singlet state of purine. Photochemistry and Photobiology 23(5): 365-368

The 1(.pi.* .rarw. n) transition of purine isolated in inert gas matrices is reported. The transition, which exhibits considerable vibronic structure, appears in the 290-330 nm region of the purine phosphoresence excitation spectrum on the long wavelength side of the 260 nm 1(.pi.* .rarw. .pi.) transition. The transition is analyzed and vibrational assignments for the 1(n, .pi.*) state are given.

Rovibrational bound states of the O(2)((3)Σ(g)(-), v = 0)-O(2)((3)Σ(g)(-), v = 0) dimer in its singlet electronic state have been obtained by solving the time-independent Schrödinger equation for the nuclear degrees of freedom. We have employe...
