Bathochromic shift is a phenomenon seen in molecular spectra, not atomic spectra; it is thus more common to speak of the movement of the peaks in the spectrum rather than lines.

A bathochromic shift refers to the phenomenon where the absorption spectrum of a molecule shifts to longer wavelengths, indicating that the energy required for electronic transitions has decreased.

The bathochromic effect refers to the phenomenon where the addition of substituents to an aromatic ring, such as in benzene derivatives, results in a shift of the UV absorption maximum to longer …

Jun 25, 2025 · What is the Bathochromic Shift? The bathochromic shift (also called a “red shift”) describes how light absorption moves toward longer wavelengths (lower energy) as molecular …

Bathochromic shift refers to the phenomenon where the absorption or emission peak of a molecule shifts towards a longer wavelength or lower energy, respectively.

Dec 29, 2009 · If as substance shifts to a lower energy state with a longer wavelength, it is referred to as a Bathochromic shift or (also called) red shift. The color will move more toward the red. Conversely, …

For an absorption peak starting at λ max = 550 nm, a shift to higher wavelength such as 650 nm is bathochromic, whereas a shift to lower wavelength such as 450 nm is hypsochromic.

plural -s : an atom or group that when introduced into a compound (such as a dye) causes a visible deepening of color (as from yellow toward green) contrasted with hypsochrome bathochromic …

Jun 5, 2019 · Bathochromic shift is a favourable condition where the reduction in energy gap makes the transition more possible. That’s why this shift is often associated with increases in the molar …
