Microwave Rotational Spectrum of Indium Monofluoride

Abstract

Abstract The rotational transitions J = 1 → 2 and 2 → 3 were measured in 115In19F. From these spectra the following molecular parameters have been determined: the Dunham-coefficients Y01, Y11 and Y02, the quadrupole coupling constants, eqQ, in the ν = 0 and v = 1 vibrational states as well as the spin-rotation coupling constant cIn.
