摘要：

Twenty one laser lines of the 250-1000 GHz range have been assigned in the v6 and v8 excited states of the H12COOH molecule. The microwave study of these two states has allowed us to determine the molecular constants and to calculate the energy levels up to J = 50. The values of the energy levels of the ground state are well known and allow the frequency calculation of infrared rovibrational transitions near the 9.6-10.6 μm region and the comparison with the frequencies of the CO2 laser lines. A microwave infrared double-resonance experiment has also been performed to confirm assignment based on the calculation of the energy levels. The value of the two band centers has been determined. © 1979.
