" /> half-width - CISMeF





Preferred Label : half-width;

Detailed label : half-width of a band;

IUPAC acronym : FWHM;

IUPAC definition : 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.;
