Ab initio calculations are used to examine the energetics of unimolecular and water-mediated decomposition of cf 3 oh into cof 2 and hf the calculations indicate that the barrier to unimolecular decomposition is large (42 ± 3 kcal mol-1) and that the rate of this reaction is negligible at room temperaturethis reaction is of no importance under ambient atmospheric conditions. Alcohol can aggravate wind – for interior wind patterns like epilepsy, tremors, strokes, and high blood pressure, alcohol can be dangerous however, in some exterior wind invasion like the onset of a cold a hot toddy can help open the pores and ‘release to the exterior’ to push the pathogen out.
