High-Resolution Instrumentation: Advantages and Applications

Abstract

Until comparatively recently, infrared spectrometers capable of high resolution have not been commercially available. Until the mid-1950’s, the single-prism NaCl instrument bore the greater part of the load in most infrared laboratories. This is still true to a great extent, but recent technological developments have made available on a commercial scale instruments capable of 1 cm⁻¹ resolution and, in some instances, resolution of 0.25 cm⁻¹. It is the purpose of this paper to discuss high resolution, the instrumental factors governing resolution, its advantages, and some of its applications.
