The full width of a spectral band at a height equal to half of the height at the band
maximum. Also known as full width at half maximum (FWHM)
. The dimension of band width should be either inverse length (wavenumbers) or inverse
time (frequencies) so that the values give an indication of the energies. Note the
hyphen in half-width. Half bandwidth has the meaning of half-width at half maximum.
