Choice of the informative parts of the rotational raman spectrum when measuring gas temperatures in the range 300–1200°K

The question of choosing the most informative parts of the rotational Raman spectrum for purposes of temperature measurements is considered, and to this end relationships for calculating the theoretical accuracy of temperature determination are derived. The results of some practical calculations relating to the measurements of air temperature at 300–1200°K are presented.Translated from Izvestiya Vysshikh Uchebnykh Zavedenii, Fizika, No. 1, pp. 116–119, January, 1977.
