Abstract
The high resolution infrared emission spectrum of BeF2 was observed. The fundamental antisymmetric stretching mode ν3 and numerous hot bands involving ν1 and ν2 were found near 1550 cm−1 by Fourier transform spectroscopy. Eight vibration–rotation bands were rotationally analyzed and the spectroscopic constants are reported. The equilibrium beryllium fluorine distance (re) was found to be 1.372 9710(95) Å in BeF2.Keywords
