{wiki=Hyperchromicity}
Hyperchromicity refers to an increase in the absorbance of light (usually in the ultraviolet-visible spectrum) by a substance, typically nucleic acids like DNA or RNA, when they undergo conformational changes. This phenomenon often occurs during processes such as DNA melting (denaturation), where double-stranded DNA unwinds into single strands.
