The current capability of high resolution, high wave-number accuracy infrared instruments offers the potential for conveniently studying very subtle (one or two cm−1) band displacements as a function of structure or solvent (1). For measurements of tenths of
cm−1 accuracy, it has formerly been necessary to calibrate the instrument carefully, using the known locations of the rotational bands of various light gases (2) and also to know the repeat-ability of the instrument to allow for errors in temperature variation, mechanical
linkages, etc. The built-in accuracy of some of the newer instruments makes this procedure unnecessary.
