Abstract:

The broadening of second derivative Gaussian and Lorentzian absorption lines has been calculated as a function of modulation amplitude. It is shown that Lorentzian lines are more sensitive to modulation-induced distortion than Gaussian lines. For modulation levels less than 0.2 half-width at half-height, broadening is less than 1 for Gaussian lines and 2 for Lorentzian lines. Author
