(A)xq6(488 nm) aux trois longueurs d'onde étudiées (Tableau A3-1) Compte tenu de la définition de S @qA3-8), la valeur faiblement positive obtenue à 633 nm indique qu'à cette longueur d'onde la section efficace du polaron vaut un peu plus du double de celle du bipolaron. En revanche, à 785 nm, la section efficace d'absorption du bipolaron étant beaucoup plus faible que celle du polaron ,
