LABORATORY INVESTIGATIONS OF THE INTERSTELLAR RADIO-FREQUENCY LINES OF CH AND OTHER MOLECULES,

Abstract

The 0-0 band of the 2 delta-2II transition of CH has been remeasured from high-dispersion plates and more precise values of the lambda doubling in the 2II state have been determined. From these optical measurements, the transition between the two components of the lowest rotational level can be predicted to lie at 3 400 Mc/sec. The possibility of finding CH and also other molecules in interstellar space by radio-frequency astronomical observations is discussed. (Author)
