On the dimers of the VIB group: a new NIR electronic state of Mo2

Abstract

Laser vaporized Mo 2 is trapped in solid neon at 7 K and investigated by optical spectroscopy using a Fourier transform spectrometer. Besides the well known A 1  ← X 1 and a( 3 Λ) → X 1 transitions, a new NIR transition, denoted as a 3  → X 1 based on DFT calculations, is detected with the help of optical absorption and laser induced fluorescence spectroscopy. The visible A 1  ← X 1 transition of the mixed CrMo is observed for the first time in the gas phase using cavity ringdown absorption spectroscopy.
