에탄 분자의 적외선 스펙트럼의 이론적 합성 = Infrared Spectrum of the Ethane Molecule

다국어 초록 (Multilingual Abstract)

The ν_6 band of the ethane gas molecule was theoretically synthesized. The intensity and the frequency of each rotational line were computed with VAX-11 computer.
The theoretically synthesized spectrum was compared with the experimentally obtained spectrum, which was taken through FT-IR spectrophotometer MX-3600.
The R and P branches of the ν_6 band contour of the ethane gas molecule were different from the regular symmetrie top molecule and rather similar to the linear molecules as if there were no K dependence.
The absorbance of the P-branch spectrum was overlapped by the unknown branches of the neighbour bands
The intensities and frequencies of the unknown lines were not indentified.
The overall band contour of the observed spectrum was quite well coincided with the theoretical spectrum except the P-branch.
