Careful control of instrument parameters and the use of a computer program for integration gives a reproducibility of <±2% between intensity measurements of reasonably isolated absorptions on different grating spectrometers in different laboratories.

Contrary to the implication in Ref. 2, we now find that the peak is a composite of two overlapping Gaussian-Lorentzian peaks.

Spectra from the PE521 still contained water absorptions after balance had been achieved.

We hope later to be able to report a simple system that allows this to be done automatically and the results directly transmitted to a computer. The spectra were digitized every cm−1 (PhNMe2) or 0.5 cm−1 (PhF and TCB).
