1π → 1π* ultraviolet absorption bands and electronic charge transfers in singlet excited states of sulfur aromatic heterocycles
(2005)
Indoline-2-thione (BC), benzimidazole-2-thione (BN), benzoxazole-2-thione (BO), and benzothiazole-2-thione (BS) define an interesting series of aromatic compounds containing a NCS synthonic unit in a heterocyclic ring of ...
Ultraviolet absorption bands and electronic charge transfers of salicylideneanilines in singlet excited states
(MARCEL DEKKER INC, 2001-01-12)
Salicylideneaniline presents an electronic absorption band spectrum of complex patterns between 200 and 450 nm. However, we have successfully developed the electronic transition assignments of this molecular compound and ...
