The disappearance of the exciting‐wavelength dependence of the phosphorescence spectra of polar, aromatic chromophores in supercooled glycol–water mixtures is utilized to monitor the kinetics of solvent reorientation. Reorientation times in the n

Heavy atoms, such as bromine or iodine, perturb the excited-state properties of aromatic chromophores through a spin-orbital coupling mechanism. In the present work the use of specifically directed spin-orbital probes to study subtle structural relat

The emission spectra of polar aromatic molecules in rigid, polar solution are shown to depend on the exciting wavelength. Occurrence of the phenomenon depends on both the excited-state lifetime of the chromophore and the degree of rigidity of the med

A DNA-dependent ATPase formed after T4 phage infection is purified to apparent homogeneity. The molecular weight of the purified enzyme is 50 000 when determined by glycerol gradient centrifugation and by sodium dodecylsulfate/polyacrylamide gel elec
