Decay of the CO fluorescence obtained under narrow-band excitation of "essentially singlet" and "essentially tipIet" rotationai Ievels resulting from the A ' II@ = 0)-e 3Z-(u = I) perturbation have been studied as a function of added rare gas pressure. Anomalous decay curves are discussed in terms o

A model is proposed for colhsion-induced intersystem crossing in "intermediate case" and small moieccules. The collisions are assumed to cause dephasing (Tz) among the zero order singlet and triplet molecular states. The combined effect of the intramoIecu!a.r spin-orbit coupling (H) and the coUision
It is found that intersgstem crossings between the singlet and the MS = fl components of the triplet state of radical p&in liquids can produce nuclear and electron spin polarizations when two radicals diffuse apart follOWing arl initial encounter and subsequently undergo a second nonreactive encount
