“Pseudo-parallel” infrared bands of oblate symmetric tops NF3 ν4 and (ν4 + ν2), and CF3Hν6

摘要: Abstract The high resolution data on the NF 3 ν 4 and ( + 2 ) infrared bands CF H 6 band have been investigated in detail using an l -type resonance calculation computer program. By means of simulation technique, shapes observed P , Q R branches are accurately reproduced frequencies all fine structure “lines” precisely matched. analysis has provided accurate values constants whose determination is not possible from microwave. signs q established unambiguously. A investigation shown that branch ariseprimarily clusters closely spaced K J lines a given these peaks generally correspond to ⋍ components clusters, respectively. differences between our those previous work found be remarkably small. This explained terms investigation.
