    Both NAD + and NADH strongly absorb ultraviolet light because of the adenine. For example, peak absorption of NAD + is at a wavelength of 259 nanometers (nm), with an extinction coefficient of 16,900 M −1 cm −1. NADH also absorbs at higher wavelengths, with a second peak in UV absorption at 339 nm with an extinction coefficient of 6,220 M ...
