hypochromic effect
The absorption spectra of the DBBIs in the presence of different DNA concentrations showed a hypochromic effect and a small shift of the absorption band to longer wavelengths, which indicated the formation of a complex with DNA.
      
Upon the introduction of the salt in concentrations below 0.15 M, the spectrum undergoes a hypochromic effect, without modification of its general shape.
      
In addition to the hypochromic effect, a new broad RLS band emerges at ~420-460 nm, which arises from large H-aggregates of the dye.
      
The ultraviolet absorption spectra indicated that the addition of Hg2+, Ce3+, and the mixture of Ce3+ and Hg2+ to DNA generated an obviously hypochromic effect.
      
The size of the hypochromic effect and the peak shift of DNA by metal ion treatments was Hg2+>amp;gt;Hg2++Ce3+>amp;gt;Ce3+.
      
The bathochromic shift of this band occurs at smaller distances between the two ethylene molecules than the hypochromic effect.
      
Two new reagents, nitrosobenzene (PhNO) and p-nitro-nitrosobenzene (p-NO2-PhNO), have been studied for the analysis of ascorbic acid (AA) by its hypochromic effect on the reagents.
      
The maximum value of the hypochromic effect in the near ultraviolet maximum was higher for complexes of denatured DNA than for complexes of native DNA.
      
A hypochromic effect was observed in the absorption spectrum of amphotericin B in the presence of albumin with maxima at 366 nm, 385 nm, and 408 nm, which correspond to the absorption of the monomeric form of amphotericin B.
      
According to the emission spectra recorded in the absence and presence of ct-DNA at different ratios r ([compound]/[polynucleotide]), 4 showed marked decrease in the fluorescence intensity and very strong hypochromic effect.
      
A specific Raman hypochromic effect may also be accompanied by a small but detectable shift in the frequency ofthe band center.
      
It has been demonstrated that spherical RNA viruses show a hypochromic effect due, presumably, to ordered configuration of the RNA.
      
Simultaneously, there was an obvious hypochromic effect observed in the 400-500 nm region of the flavin absorption spectrum.
      
The decrease n-as maximal in the middle of stage II, butt with fuirther fixation the hypochromic effect diminished.
      
The highest values for dyes 1 and 3 correlate well with the hypochromic effect of the dyes in LC matrix.
