The infrared absorption spectrum of carbon disulfide has been remeasured in the region from 2 to 24 I' with cells up to 5 mm in t hickness. Fifteen bands were observed , some however being of low intensity. The strongest band for the liquid occurs at 6.621' , and t he second harmonic of this band was observed at 2.22 1' , but t he first harm onic, which should be at about 3.33 1' , was not obse...

A series of benzimidazole-2-thione derivatives was synthesized using a reaction between the macrocyclic aminal 16H,13H-5:12,7:14-dimethanedibenzo[d,i]-[1,3,6,8] tetraazecine (DMDBTA, 5) and various nucleophiles in the presence of carbon disulfide. A full chemical characterization using IR, ¹H-, ¹³C-NMR and GC-MS analyses of the new compounds is provided. These compounds were separated from the ...

A gas-chromatographic analysis of vinylidene chloride (1,1-dichloroethylene) is presented. Vinylidene chloride was sampled by adsorbing on activated carbon. It was desorbed with carbon disulfide. The desorption efficiency was 97.2 +/- 1.05 (mean +/- standard error). The analytical column was packed with 10% Apiezon L on acid-washed Chromosorb-P. The analysis was conducted on a gas chromatograph...
