Through the use of the electron spin echo envelope modulation method, we have accomplished the complete determination of the14N hyperfine and quadrupole interaction tensors in the lowest photohyphen;excited triplet state of freehyphen;base porphin in annhyphen;octane single crystal at sim;1.4 K. The results give insight into the molecular structure of the porphin in the excited state, the relationship between the nitrogen spin density and observed hyperfine couplings, and the effect of hydrogen bonding interactions on the quadrupole coupling constants and principal axes.
