Les hélices [alpha] d'une protéine sont des conformations orientées avec une régularité certaine dans l'arrangement périodique de liaisons identiques. En outre, les groupements chromophores de la région hélicoïdale conduisent à la formation d'un système d'excitons. Sous l'action d'un rayonnement, la molécule est excitée (oscillations, transitions électroniques, etc.). Les interactions de résonance influent à la fois sur l'absorption et sur la rotation de la lumière. [...] Les lois de Drude, de Moffitt, quantifient la rotation optique en fonction des paramètres du milieu.
