On 21 January, the Climate Change Committee decided, on the basis of a proposal for a decision presented by the European Commission, on 25 November 2010, to strengthen the rules applicable to CDM appropriations following investments in projects that aim to reduce two industrial gases - trifluoromethane - HFC-230, which results from the production of chlorodifluoromethane (HFC-22) and nitrous oxide (N20), a by-product of fluoroform (HFC-23).
Initially, one important structural observation in (I) and (II) is the contraction of -0.0004 [Angstrom] and -0.0003 [Angstrom] for the r(C-H) bond of the fluoroform, as well as the changes on its [upsilon](C-H) frequencies which are shifted upward to values of 2.8 [cm.sup.-1] and 1.3 [cm.sup.-1] followed by a substantial diminution in absorption intensities, e.g., ratios of 0.2 and 0.17.
Sturges and his colleagues recently reported the presence of fluoroform ([CHF.sub.3]), and he says he's convinced that other greenhouse gases in low concentrations are yet to be identified.
