P. Geissinger et al., INTERNAL ELECTRIC-FIELDS AND INHOMOGENEOUS BROADENING - PROTOPORPHYRIN-IX IN MYOGLOBIN, Molecular crystals and liquid crystals science and technology. Section A, Molecular crystals and liquid crystals, 283, 1996, pp. 69-74
Estimates of the relative contributions of dispersive and electrostati
c interactions to the solvent shift of the Q(x) excitation energy of p
rotoporphyrin-IX in myoglobin are derived from measurements of the dep
endence of Stark splitting on frequency.
