摘要

激光汽化的二氧化钼在7 K时被捕获在固体氖中,并用傅里叶变换光谱仪对其进行了光谱学研究。除了已知的a1←x1和A (3 Λ)→x1跃迁外,利用光学吸收和激光诱导荧光光谱检测到一种新的近红外跃迁,基于DFT计算表示为3→x1。利用腔衰荡吸收光谱首次在气相中观察到混合CrMo的可见a1←x1跃迁。

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