The analytical expression describing the dynamics of nuclear magnetization with the use of double-resonance NMR by the procedure of inverse fractional population transfer in requirements of photo-induced chemical exchange (PICE) is obtained in this article. Laser-induced (λ = 308 nm) photoisomerization of 1,2-(2,2′-dipyridyl)ethene was studied by NMR and UV absorption spectroscopy under irreversible and photostationary conditions.
