A METHOD OF CALIBRATING AND INFRARED PRISM SPECTROMETER
W. L. Ross, Dianne Little · The Knowledge Bank (The Ohio State University) · 1951
This calibration method, developed for a Perkin-Elmer Model-12 spectrometer, covers the regions 5 to $15 \\mu (NaCl)$ and 2 to $5 \\mu (LiF)$. Standardized techniques lowered the standard deviation of the spectrometer itself to $0.10 cm^{-1}$ at $1000 cm^{-1}$. The McKinney and Friedel formula, $T_{1} = T_{0} + \\frac{*}{v_{1}{^{2}} - v_{1}{^{2}}}$, is shown to be analogous in form and method of solution to the Hartmann dispersion formula, $\\lambda_{1} = \\lambda_{0} + \\frac{c}{d_{0} - d_{1}}$. Thus Hartmann-formula techniques have been applied to the McKinney and Friedel equation. Solutions are readily handled on a calculating machine; graphical interpolations are obviated. The results have a standard deviation of $0.28 cm^{-1}$ at $1000 cm^{-1}$.
