Example sentencesExamples
In the case of the model compound of tyrosine NAYA, a small bathochromic shift of 2 nm in the emission spectrum from dioxane to water was observed.
The physical origins of this bathochromic shift are described in detail in molecular spectroscopy texts.
In particular, the dianion absorption spectrum exhibits a substantial bathochromic shift and a reduction in bandwidth in solvent-water mixtures containing aprotic solvents as the hydrogen-bonding environment is decreased.
Furthermore, the substitution reactions resulted in small bathochromic shifts in the absorption spectra.
After photoisomerization, a bathochromic (red-shifted) intermediate, called K, forms in 3 ps.
Origin
Late 19th century: from Greek bathos 'depth' + khrōma 'colour' + -ic.
