Abstract
A large number of emissions is obtained in the submillimeter and near millimeter range with the (H2CO)3 laser optically pumped by a CO2 laser. A study of the microwave absorption spectrum of the molecule carried out simultaneously with the submm analysis allows us to assign six of the laser lines in thev 5 excited state of the molecule and to determine the rotational constants and vibrational energy ofv 5.
