Abstract
A continuously tunable single frequency color center laser spectrometer has been applied to analyze the rovibrational gas phase spectra of the fundamental ν2 (C–H stretching vibration) and its hot bands ν2+ν4−ν4 and ν2+ν17−ν17 in the linear dimer HCN‐‐‐HF. The l‐type doubling constants q″v and qv of the Π←Π band are both determined to be 12.4(8) MHz and anharmonic cross terms X024 and X027 are evaluated as −0.1656(17) and +0.1310(35), respectively from the available data. Excited state amplitude lifetimes in the ν2 band are demonstrated to be 1.3(4)×10−8 s.Keywords
