Question: In which of the following compounds could bathochromic shift occurs? Explain your answer. A) 2,4-DNP B) Fluorescein. In which of the following compounds could bathochromic shift occurs? WebBathochromic shift (from Greek βαθύς bathys, "deep"; and χρῶμα chrōma, "color"; hence less common alternate spelling "bathychromic") is a change of spectral band position in the absorption, reflectance, transmittance, or emission spectrum of a molecule to a longer wavelength (lower frequency). Because the red color in the visible spectrum has a longer …
