shift at 220 nm was detected in resin in the first 2 bands and observation of a new band in resin as compared to the Schiff base owing to polycondensation and supports the establishment of resin as shown in Table II.
The most important information regarding the coordination site in morin can be easily observed from UV-visible spectra, which show that 1: 1 interaction in metal: morin causes the bathochromic
shift in both bands.
Specifically, phenolic compounds with two or more vicinal hydroxy benzyl moieties in their structure, such as catechols and pyrogallols, were examined for their ability to give spectral bathochromic
shift phenomena when mixed with iron salts.
The transition had undergone bathochromic
shift toward visible region due to coordination effect.
Namely, a bathochromic
shift of the absorption band maximum (about 10 nm) was observed in the visible region before swelling.
From the figure one can see that the spectra show bathochromic
(or red) shift.
In the latter approach, acid-base interactions in the substrate-catalyst complex will lead to a significant bathochromic
absorption shift of the substrate, enabling a selective excitation within the complex and a subsequent enantioselective reaction pathway within a spatially defined chiral environment.
The large bathochromic
shift of 2, compared to TPA, is due to the larger conjugation of compound 2 that lowers the energy level of the n* orbital.
In all spectra the electric field produced bathochromic
shift of the bands.
Minor changes in the absorbance pattern of the target molecule were observed in different solvent environment whereas a significant bathochromic
shift was found for fluorescence.
shift in band II after addition of NaOAc indicated the glucosylation of 7-OH.
The plants with the bathochromic
phytochromes are expected to respond to canopy and shade conditions for growth and development with greater efficiency than the plants with wild-type phytochrome (i.
