摘要：

Photophysical kinetics of phthalazine (F, 2,3-diazanaphthalene) and conjugate acids (FH+, FH++2) were determined. According to CNDO/S CI calculations, first protonation only slightly changes the energy of the first (n, π*) state. Some (σ, π*) states are lowered upon protonation. In contrast to protonated 1,4-diazines, FH+ and FH++2 are not distorted in excited state. © 1979.
