sorption coefficients are wrong in Table II. In this table the J values of the CO2 00°l-02°0 (9-μm band) are mislabeled: the absorption coefficients attributed to the P6 line are those of the P8, etc. This has been verified for C2H4, C6H6, and NH3 and is very probably so for the other gases, since the mistake comes from a wrong calibration of the laser grating. For C2H3C1 new measurements gave slightly different values. The correct table is given below.
