Herein, a slight hypsochromic shift was observed in the inclusion process of CB7/luteolin and CB7/EGCG.
As the temperature was increased from 40[degrees]C to 80[degrees]C, a blue shift (hypsochromic shift) occurs due to reduction in the size of particles from large size to small size.
The hypochromic shift (lower absorbance) at 430nm and appearance of new peak at 308nm (hypsochromic shift) indicated reduction.
DTU exhibited bathochromic shift of about 8 nm, whereas, 2-TU demonstrated a hypsochromic shift followed by bathochromic shift as the concentration of CTAB increased from pre-micellar to micellar concentration.
Table 4 and Figure 3 show that regression coefficients y and b ([c.sub.1] and [c.sub.2]) in all the equations obtained are positive; hence, the increase in the polarity and the nucleophilicity of the medium results in a hypsochromic shift of the longwavelength absorption band.
The unsymmetrical combination of hetero cycles with different basicity in Heptal, Hepta2, Hepta3, Hepta4, and Hepta6 causes a symmetry break resulting in a slight hypsochromic shift of the [[lambda].sub.max] value, a noticeable decrease of the extinction coefficient [epsilon] at [[lambda].sub.max], and additional weak absorption at around 400 nm.
Photophysical analysis shows that both the maximum absorption and photoluminescence spectra of P[F.sub.10]-P2V[P.sub.35], P[F.sub.10]-P2V[P.sub.55], and P[F.sub.10]-P2V[P.sub.75] thin films exhibit a hypsochromic shift with an increase in MeOH from 0-90 vol.%.
The ortho dihydroxyl group in ring B was detected by a hypsochromic shift of band I after addition of Al[Cl.sub.3]/ HCl compared to Al[Cl.sub.3] spectrum (ca 25 nm).
Despite this, for PPME the maximum peak ([[lambda].sub.max] = 675 nm) is hypsochromic shift with regard to that of PPa ([[lambda].sub.max] = 676 nm).
Furthermore the dye molecules are arranged in a parallel and stacked manner within the aggregates resulting in a hypsochromic shift [47].
