Abstrakt: The rotationally resolved spectrum of the (000–000) B 2A‘–X 2A’ band system [T000–000=15 859.4638(15) cm-1] of a supersonic molecular beam sample of calcium monohydrosulfide, CaSH, was recorded in the presence of a variable static electric field. The magnitude of the a-principal axis component of the permanent electric dipole moment, |μa|, was determined to be 5.36(4) and 3.78(7) D for the X 2A’ and B 2A‘ states, respectively. An analysis of the field free spectra produced values for the (000) B 2A‘ vibronic state fine structure parameters of (in cm-1); A’=10.433 56(16), B’=0.143 43(15), C’=0.141 14(15), εaa=-5.779 3(19), εbb=0.107 67(88), and εcc=0.032 70(83). An interpretation of the parameters is presented. [ABSTRACT FROM AUTHOR]
