Vibrational spectra and trace determination of p-difluorobenzene and ethylbenzene.

Spectrochim. Acta. A. Mol. Biomol. Spectrosc. 107 , 1-7, (2013)

In this work, the structures and normal vibrations of p-difluorobenzene and ethylbenzene in the first excited state have been studied using resonant two-photon ionization spectrum and ab initio quantu...

Ionized o-, m-, and p-difluorobenzene dissociate through ring-opened intermediates: a TPEPICO investigation.

J. Am. Soc. Mass Spectrom. 20(1) , 20-4, (2009)

Threshold photoelectron photoion coincidence (TPEPICO) experiments have shown that o-, m-, and p-difluorobenzene ions dissociate via a common, ring-opened intermediate and not via ionized p-difluorobe...

Regioselectivity of cytochrome P-450 catalyzed hydroxylation of fluorobenzenes predicted by calculated frontier orbital substrate characteristics.

Biochemistry 32(18) , 4801-12, (1993)

In the present study, a hypothesis is presented for the prediction of the regioselectivity of cytochrome P-450 catalyzed hydroxylation of fluorobenzenes. The regioselectivity of the in vivo hydroxylat...
