Summary

Two alternative forms of the CO2 molecule have been suggested by various authors who have discussed the band spectrum data. The specific heat curves based on these models are considered here. It is found that neither is quite satisfactory over the whole range of temperature and we discuss the difficulties for the low temperature and high temperature portions separately. In order to get agreement for low temperatures we find it necessary to introduce a further hypothesis about the molecular model which also seems to explain one or two outstanding difficulties in interpreting the fine structure of the bands. This assumption does not make any difference at higher temperatures where we show the error in one of the curves to be of the order we should expect to be accounted for by a centrifugal stretching of the molecule.

* Schaefer and Philipps remark that the band which they tabulate as 2ν2 – ν1 may alternatively be given as ν2 + 2ν3. It is a double doublet and forms the only possible exception to what is said above. On our theory the two lines of the n series in ν2, for example, will be due to switches in n of 1→2 and 2→1 (requiring again C ≅ 1·5 × 10−40) and we still cannot explain why more lines of the series are not observed.
