Introduction to Spectroscopy
Substitution on the carbonyl group by an auxochrome with a lone pair of
electrons, such as INR2, IOH, IOR, INH2, or IX, as in amides, acids, esters, or acid
chlorides, gives a pronounced hypsochromic effect on the n U p* transition and a
lesser ...

Hyperehromic fm.n Hypsochromic Bathochromic Absorption band Wavelength
Fig. 2.5 Shifts in absorption position and intensity Hypsochromic Shift or Effect.
The shift of an absorption maximum to a shorter wavelength is called
hypsochromic ...

Essentials of Pharmaceutical Chemistry
A shift in λmax to shorter wavelength is called a hypsochromic effect, or blue shift,
and usually occurs when compounds with a basic auxochrome ionise and the
lone pair is no longer able to interact with the electrons of the chromophore.

Protein Sequencing Protocols
A hypsochromic shift of the aromatic ring absorption maximum of tyrosine can be
observed when the phenolic hydroxyl group is modified with a phosphate moiety.
Likewise in the second- order derivative spectra a hypsochromic shift of the ...

Undergraduate Instrumental Analysis, Sixth Edition
A shift to shorter wavelengths is called a hypsochromic shift or blue shift. An
increase in the intensity of an absorption band (that is, an increase in 1max )
iscalledhyperchromism; a decrease in intensity iscalled hypochromism. These
shifts in ...

(2000) observed that conjugation of the hydroxyl group at position 3 of quercetin
causes a Band I hypsochromic shift of around 12–17 nm, whereas a shorter
hypsochromic shift (3–5 nm) occurred when conjugation was at position 4, and
no ...

The addition of a sugar residue to the anthocyanidin 3-position produces in
general a hypsochromic effect of 10–14nm in the visible region of the absorption
spectra, depending on the solvent and nature of the aglycone. The nature of the ...
For the bis(benzo- thiazolylidene)squaraine, such as 5 (Scheme 2), however,
complexation with alcohol solvents brought about marked hypsochromic shifts in
its absorption and emission maxima [62] (Figs. 1A and B). The hypsochromic
shifts ...

However, its peak showed a hypsochromic shift from λmax = 672 to λmax = 653
nm with increasing C from 1 × 10–3% to 2% (Fig. 9.8). Squarylium dyes, owing to
intra-ionic structure, are chemically bound by a nondissociating contact ionic ...

Engineering Chemistry with Laboratory Experiments
Hypsochromic shift: The decrease in absorption intensity due to the shifting of
wavelength from higher to lower region (higher energy) is called hypsochromic
shift. This is also called blue shift and causes due to the substitution or solvent
effect ...
