摘要：

Polarized fluorescence excitation and dispersed fluorescence spectra of 3-methylindole (3MI), 5-methylindole (5MI), and 2,3-dimethylindole (2,3DMI) in solid Ar at 20 K under site selective conditions have unambiguously revealed their (1)L(a) origin locations. For 3MI the (1)L(a) origin is 260 cm(-1) above the (1)L(b) origin and for 5MI it is 1800 cm(-1) above (1)L(b). For 2,3DMI, the (1)L(a) origin lies 190 cm(-1) below the (1)L(b) origin. The latter assignment is made from details of the dispersed fluorescence in comparison to the phosphorescence spectrum of indole in argon at 20 K.
