1,2-Dichloro-1,1-difluoroethane (HCFC-132b) is a potential substitute for some ozone-depleting chlorofluorocarbons and a model for other 1,1,1,2-tetrahaloethanes under consideration as chlorofluorocarbon substitutes. Male Fischer 344 rats were given 10 mmol/kg HCFC-132b dissolved in corn oil by intraperitoneal injection. An NMR assay

Increased UV-B through stratospheric ozone depletion leads to an increased chemical activity in the lower atmosphere (the troposphere). The effect of stratospheric ozone depletion on tropospheric ozone is small (though significant) compared to the ozone generated anthropogenically in areas already

The reorientation of CClF2 groups in N(CH3)4H(ClF2CCOO)2 has been studied using pulsed NQR and NMR techniques. The temperature dependence of both chlorine (35Cl) NQR and fluorine (19F) NMR spin-lattice relaxation has been measured T1Q of chlorine is attributed to the

Chlorodifluoroacetic acid (CDFA) is a novel haloacetic acid (HAA) and has been recently documented in aquatic systems. It is a suspected degradation product of the refrigerants 1,1,2-trichloro-1,1-difluoroethane (CFC-113) and 1-chloro-1,1-difluoroethane (HCFC-142b). Haloacetic acids can be phytotoxic, putatively acting through inhibition

Negative ion formation following resonant electron attachment to the three title molecules is studied by means of a beam experiment with mass spectrometric detection of the anions. All three molecules exhibit a pronounced resonance in the energy range around 1
