... Investigation of the absorption electronic spectrum of the monobromide hafnium molecule in the region 550–800 nm . Abstract The absorption electronic spectra of HfBr in the region550–800 nm have been obtained and investigated using the intracavity laser method. ... Twenty new bands contained partly resolved rotational structure were found in the HfBr spectrum as a result of the high sensitivity of the intracavity method. ...
