Experimental and calculated cross sections for pressure broadening of pure rotational Raman lines of HCl

The pure rotational Raman transitions J = 0 → 2 through J = 5 → 7 of HCl have been measured. Results are presented for HCl without admixture at 1 atm and 300 K, and for HCl with argon at pressures of about 10 and 20 atm. The HCl self-broadening is compared with earlier results. The linewidths of HCl broadened by argon are compared with the result of calculations. Cross sections are calculated based on different potentials which have been suggested for the Ar---HCl system

Strontium and lead isotope ratios in human hair: investigating a potential tool for determining recent human geographical

Three cleaning techniques that remove external contamination of human hair are assessed to investigate the potential use of Sr and Pb isotope composition of hair for human provenancing. These techniques are; (i) a centrifugation technique using diiodomethane where hair and soil particles are separated by density difference; (ii) a leaching technique of the hair surface using 2 M HN

Identification of the geographical place of origin of an unidentified individual by multi-isotope analysis

A multi-isotope investigation (Sr and Pb isotopes and δ18O, δ13C and δ15N) was applied to bone and teeth from an unidentified male found drowned in the"IJ" Ruyterkade in Amsterdam, The Netherlands in March of 1999. The individual remained unidentified until mid 2013, after the isotope study was completed. Coupled δ13C and δ15N values in bone collagen recovered from rib and femur are consistent with an omnivore living in a region where C3-type diet dominates (i.e. Europe). Integrated Sr and Pb isotopes and δ18O values in canine and third molar teeth and femur and rib bone data exclude extended residence in north-west Europe and particularly The Netherlands. Characteristic Pb isotope ratios coupled with inferred δ18O values of drinking water argue for a most probable place of origin for the unidentified individual in west and south Poland, south-east Slovakia and the region of Ukraine-Romania-Bulgaria, specifically the region associated with the Carpathian Mountains. Independent of the isotope study, the Cold Case Team made a positive identification with an individual from south-west Poland, validating the results of the multiple-isotopic approach
