Rotational Spectrum, Structure, and Interaction Energy of the Trifluoroethylene···Carbon Dioxide Complex.

Rotational spectra for four isotopologues of the 1:1 weakly bound complex between trifluoroethylene (HFC═CF) and carbon dioxide (CO) were recorded using 480 MHz bandwidth chirped-pulse and resonant cavity Fourier transform microwave spectroscopy between 5.0 and 18.5 GHz.

Recent tax changes may assist treatment of obesity.

The U.S. Surgeon General's Call to Action on Overweight and Obesity 2001 proposes inclusion of health care providers in prevention efforts and suggests classification of obesity as a disease category for reimbursement coding.
