Abstract

A data recording and processing system is described which transfers gas-phase intensity data directly to punched paper tape, uses a digital computer for all phases of the data handling, and thus substantially reduces the time for the measurement of a single band. The recorder pen position is continually converted to a digital record by a shaft encoder operating at positions on the spectrometer lead screw that are determined by a Schmidt-Trigger encoder unit. Auxiliary information and data output are recorded by utilizing a series of programs that eventually generate sets of ∂p/(∂sj). The use of this system is illustrated by considering its application to a determination of the absorption band intensities of trans HFC=CFH.
