Hypsochromic effect

Japanese: hypsochromic effect（英語表記）hypsochromiceffect

...When a substituent (auxochrome) such as Cl, NH ₂ , or NO ₂ is introduced into such a molecule, or when other unsaturated bonds are added, the π-electron conjugation system becomes larger, and the bathochromic effect appears. The opposite effect of the bathochromic effect, which shifts the spectrum to the shorter wavelength side, is called the hypsochromic effect. Red-shifted π bond [Yoshiya Harada]. ...

…このような分子にCl,NH₂,NO₂等の置換基(助色団)が導入されたり，また他の不飽和結合が加わったりしてπ電子共役系が大きくなると深色効果が現れる。深色効果と逆にスペクトルを短波長側に移動させる効果を浅色効果hypsochromic effectという。赤方偏移π結合【原田義也】。…
