Example of bathochromic shift
WebFeb 20, 2024 · Bathochromic: a shift of a band to lower energy or longer wavelength (often called a red shift). Hypsochromic: a shift of a band to higher energy or shorter wavelength (often called a blue shift). Hyperchromic: an increase in the molar absorptivity. Hypochromic: an decrease in the molar absorptivity.
