H. Korsgen et al., THE BENDING VIBRATION OF FED2 AT 226 CM(-1), DETECTED BY FAR-INFRAREDLASER MAGNETIC-RESONANCE SPECTROSCOPY, The Journal of chemical physics, 107(3), 1997, pp. 1025-1027
We report the first gas phase observation of a bending vibration in an
open shell molecule by far-infrared laser magnetic resonance. The spe
ctrum is due to FeD2; its observation shows that rovibrational transit
ions can be detected with such a spectrometer. The molecule was produc
ed in the reaction between deuterium atoms and iron pentacarbonyl. FeD
2 has a linear (5) Delta ground state and shows the effects of Renner-
Teller coupling in the excited vibrational (010) level. (C) 1997 Ameri
