Abstract

LiSr was produced in a heat-pipe oven and its thermal emission spectrum around 9300 cm-1 was recorded by a high resolution Fourier transform spectrometer. In addition, selected lines of the spectrum of deeply bound vibrational levels of the and states were studied using laser excitation to facilitate the assignment of the lines. The ground state could be described for to 2, up to 105 and the state for up to. For both states, Dunham coefficients, spin-rotation parameters and potential energy curves were evaluated. A coupling of the state to the state was observed, allowing a local description with Dunham coefficients of the state and an approximate evaluation of the coupling strength.
