What is the maximum value of the Gaussian lineshape function relative to the Lorentzian lineshape?
The Gaussian peak value exceeds the Lorentzian peak value by almost 50%
How does the sharpness of the Gaussian lineshape compare to the Lorentzian lineshape?
The Gaussian lineshape is much sharper than the Lorentzian lineshape
What is the result of convolving two Lorentzian lines with widths $_1$ and $_2$?
A Lorentzian line with width $ = _1 + _2$
What is the result of convolving two Gaussian lines with widths $_1$ and $_2$?
A Gaussian line with width $ = \sqrt{_1^2 + _2^2}$
What is the Voigt profile?
The Voigt profile is the combination of thermal broadening with natural or collisional broadening
What type of broadening is described by the Lorentzian lineshape?
Natural or collisional broadening
What type of broadening is described by the Gaussian lineshape?
Doppler broadening
Which statement about the convolution of a Lorentzian line and a Gaussian line is true?
It is always possible to reduce the problem to the convolution of a single Lorentzian with a single Gaussian line
What is the mathematical form of the Gaussian lineshape function?
$G(\nu) = \frac{1}{\sqrt{2\pi}\Delta\nu_0} \exp\left(-\frac{(\nu - \nu_0)^2}{2\Delta\nu_0^2}\right)$
