摘要: Fluorescence‐dip infrared spectroscopy (FDIRS) is employed to record the spectra of isolated, jet‐cooled tropolone molecule (TrOH) and its singly deuterated isotopomer TrOD in O–H C–H stretch regions. The ability method monitor a single ground‐state level enables acquisition out lower upper levels zero‐point tunneling doublet free from interference one another. high power optical parametric oscillator used for generation produces FDIR with good signal‐to‐noise despite weak intensity transitions tropolone. expectation that both will exhibit two OH separated by OH(v=1) splitting only partially verified present study. TrOH are compared those (TrOD) assign due O–H, which close proximity TrOH. appearance (a1 symmet...
