โฆ Synopsis
From the mtensity behaviour of a 29 cm-t Raman shift of a-A1203:Cr3+ as a tunctlon ot the incident power, it is concluded that the shift IS due to an clectromc Raman transition between the components of the excited state 'E. Population of the excited states is obtained through a pumpmg mechanism induced by the laser radiatron hp = 5 14.5 nm which at the same time sewa as a Raman probe.

The rotational spectrum of DCOOH in the 175-335 GHz region was investigated. Analysis of the spectrum made it possible to assign several dozen transitions in the n 6 , n 8 , and n 5 vibrational states and to determine the rotational and centrifugal distortion constants. The derived parameters of the
