Gn. Patwari et al., Electronic and vibrational spectroscopy of dihydrogen bonded 2-pyridone-borane-trimethylamine complex in supersonic jets, J PHYS CH A, 105(38), 2001, pp. 8642-8645
In this paper we present results of laser-induced fluorescence excitation,
fluorescence detected infrared and IR-UV hole-burning spectroscopic studies
on the 2-pyridone and borane-trimethylamine complex. A relatively small bl
ue shift in the electronic transition accompanied by a large shift in the N
-H stretching vibration to a lower frequency suggests the formation of a di
hydrogen bonded complex. The structure of the complex is elucidated with th
e aid of ab initio DFT calculations, which fits the observed spectral shift
