Název v původním jazyce

Interactions in Symmetric Top Molecules between Vibrational Polyads: Rotational and Rovibrational Spectroscopy of Low-lying States of Propyne, H3C-C.IDENT.CH.­ ­

Popis výsledku v původním jazyce

More than 700 new rotational transitions within the vibrational states v10 = 1, 2, and v9 = 1 have been recorded between 85 and 922 GHz corresponding to 4 < J´< 53. In the case of v10 = 1, high K transitions could be recorded up to Kl10 = -17 and +19, respectively, only limited by the vanishing intensities of these highly excited lines. Similarly, the v9 = 1+1 subbranch could be followed up to K = 18. Investigations of the other subbranches were limited to Ks below the ones severely perturbed by Fermi-type interactions with vibrational states of the next tetrad approximately 350 cm-1 higher in vibrational energy. Moreover, perturbations in the K = 8 stack of v5 = 1 could be traced to a Coriolis resonance with v10 = 2-2, K = 9. Several highly perturbedtransitions, including transitions between the two states, have been recorded in the submillimeter range and fit within experimental uncertainties.
