1. Hypsochromic shift

   Hypsochromic shift (from ancient Greek ὕψος (upsos) "height"; and χρῶμα chrōma, "color") is a change of spectral band position in the absorption, reflectance, transmittance, or emission spectrum of a molecule to a shorter wavelength (higher frequency). Because the blue color in the visible spectrum has a shorter wavelength than most other colors, this effect is also commonly called a blue shift. This can occur because of a change in environmental conditions: for example, a change in solvent polarity will result in solvatochromism. A series of structurally related molecules in a substitution series can also show a hypsochromic shift. 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. Δ λ = λ o b s e r v e d s t a t e 1 − λ o b s e r v e d s t a t e 2 {\displaystyle \Delta \lambda =\lambda _{\mathrm {observed} }^{\mathrm {state1} }-\lambda _{\mathrm {observed} }^{\mathrm {state2} }} where λ {\displaystyle \lambda } is the wavelength of the spectral peak of interest and λ o b s e r v e d s t a t e 1 > λ o b s e r v e d s t a t e 2 {\displaystyle \lambda _{\mathrm {observed} }^{\mathrm {state1} }>\lambda _{\mathrm {observed} }^{\mathrm {state2} }} For example, β-acylpyrrole will show a hypsochromic shift of 30-40 nm in comparison with α-acylpyrroles.
