摘要：
New bands of scandium monohydride at origins 17,914.5 and 17,9423 cm(-1) have been observed in a jet-cooled beam with laser-induced fluorescence spectroscopy. Mass-selected resonant photoionization spectroscopy also confirmed the carrier of the band as ScH. The rotational analysis indicated that both transitions at 17,914.5 and 17,942.3 cm(-1) are of Omega' = 2 - Omega" = 1 type with vibrational assignments (0,0) and (1,1) respectively. The assigned g(3)Phi(2)-a(3)Delta(1) excitation is the first observed triplet-triplet transition in ScH. (C) 2014 Elsevier Ltd. All rights reserved.
