Intensity borrowing
WebSep 1, 2024 · These forbidden transitions gain sufficient strength through the intensity borrowing effect from other transitions involving mixed resonant states. The assigned transitions include the torsional hot band, overtone band, and transitions in the second excited torsional states. The assigned transition wavenumbers have been used to obtain … WebJul 15, 1973 · In the absence of normal. mode mixing the intensity borrowed through the simultaneous action of both couplings may be written in the form [8] = w. (M~ ± w MBO)2 where j identifies the isotope (H or D in our case), the M are electronic integrals independent of vibrational parameters and the upper (lower) sign holds for ab- sorption (emission).

Rather, it is the vibronic mixing of the ground vibronic level of NO 3 with vibrational levels in the 2 E′ electronic state that permit the a ...
Webphoton E 1Π−X 1Σ+ transition is observed with intensity comparable to the allowed R-branch. The bright character of the high-J Q-branch lines can be described quantitatively as intensity borrowing due to mixing of the E 1Π and C 1Σ+ states, using J-dependent mixing coefficients extrapolated from the observed Λ-doubling in WebAug 23, 2006 · Two possible intensity borrowing mechanisms—one involving spin-orbit (s.o.) interaction of the ground sextet with the excited quartet states and the other involving the s.o. interaction of an excited charge transfer sextet with the excited quartet states—have been considered for electric dipole transitions in Tdsymmetry and for magnetic dipole …
