Název v původním jazyce

Interactions between vibrational polyads of propyne, H3CCCH: Rotational and rovibrational spectroscopy of the levels around 1000 cm-1

Popis výsledku v původním jazyce

The study of vibration resonance physics in propyne is based on experimental measurements of about 600 new rotational transitions between 495?590 and 700?760 GHz in excited vibrational levels v5 = 1,v8 = 1, v10 = 3 and v9 = v10 = 1 with vibrational energies around 1000 cm-1. The limits to the assignments and analysis were imposed by as yet unresolved anharmonic resonances with the states of the next higher polyad of levels lying above 1200 cm-1, which affect the rotational states involved in transitionsthat would be measurable with non-vanishing intensities. Vibration?rotation spectra pertaining to the levels in question were studied in the regions 880?1150 cm-1 (the m5 and m8 fundamental bands), 550?750 cm-1 (the v9 = v10 = 1 v10 = 1 hot bands) and 250?400 cm-1 (the v10 = 3 v10 = 2 ??superhot? bands). A simultaneous least-squares fit of both types of data provides their reliable but in the case of accurate rotational data not always fully quantitative reproduction.
