摘要: The spectrum of ethyl cyanide, or propionitrile (CH3CH2CN), has been repeatedly observed in the interstellar medium with large column densities and surprisingly high temperatures hot core sources. construction new, more sensitive, observatories accessing higher frequencies such as Herschel, ALMA, SOFIA have made it important to extend laboratory data for cyanide coincide capabilities new instruments. We report extensions measurements rotational its ground vibrational state 1.6 THz. A global analysis state, which includes all previous 3356 newly assigned transitions, fitted within experimental error J = 132, K 36, using both Watson A-reduced S-reduced Hamiltonians.
