| Abstract: | A FT spectrum of  3, 9 and 7 of CH2F2 is recorded and assigned between 1030 and 1230 cm–1. Coincidences with CO2 lasers are investigated.Submillimeter emissions are unambiguously assigned by a loop procedure including only IR and SMM measurements. In some cases pseudo-loops are added using ground state computed energies. In spite of the large perturbations, an exact model for excited vibrational states is not needed to ascertain SMM assignments. |
