Anotace
Almost 300 new rotational transitions within the fundamental vibrational level v(10)=1 of propyne have been measured in selected regions between 495 and 925 GHz spanning the quantum numbers 28less than or equal toJless than or equal to54 and 0less than or equal toKless than or equal to16. The accuracies are mostly between 10 and 20 kHz. In addition, the J"=4 and 5 transitions near 85 and 103 GHz have been remeasured. Simultaneous analyses with refined rovibrational data have been performed, showing that even this lowest and seemingly isolated vibrational level needs a global treatment when high K transitions are involved. The global model with the v(10)=1 level coupled to the next higher cluster of levels, v(10)=2/v(9)=1, by Fermi and Coriolis resonances is necessary for a quantitative reproduction of both the rovibrational and rotational data within their experimental uncertainties.
