WebSep 16, 2024 · Conceptually, it is as if the original spectral lines—which can be seen as Dirac impulsions—were convolved by a line-broadening profile, as depicted below. Convolution of two spectral lines by a broadening function of profile f (x). Image source. There are a number of effects which control spectral line shape. A spectral line extends over a range of frequencies, not a single frequency (i.e., it has a nonzero linewidth). In addition, its center may be shifted from its nominal central wavelength. There are several reasons for this broadening and shift. These reasons may be divided into two general categories – broadening due to local conditions and broadening due to extended conditions. Broadening due to local conditions is du…
