Bathochromic shift: In spectroscopy, the position shift of a peak or signal to longer wavelength (lower energy). … A hypsochromic shift is the shift of a peak or signal to shorter wavelength (higher energy). Also called a blue shift.

What is spectral shift in spectroscopy?

n. An increase in the wavelength of radiation emitted by a receding celestial object as a consequence of the Doppler effect. [From the fact that the longer wavelengths of light are at the red end of the visible spectrum.]

What is difference between Bathochromic and Hypsochromic shift?

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).
