hypsochromic shift

In H-aggregates a hypsochromic shift is observed with low or no fluorescence.

Hypsochromic shift, a change to shorter wavelength (higher frequency)

A series of structurally related molecules in a substitution series can also show a hypsochromic shift.

Negative solvatochromism corresponds to hypsochromic shift (or blue shift) with increasing solvent polarity.

The electronic transitions of molecules in solution can depend strongly on the type of solvent with additional bathochromic shifts or hypsochromic shifts.

Hypsochromic shift is a change of spectral band position in the absorption, reflectance, transmittance, or emission spectrum of a molecule to a shorter wavelength (higher frequency).

Hypsochromic 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.
