โฆ Synopsis
In this co~unication we report for the fist time the vapour-phase detection of carbodiimide. In the infrared spectrum of cyanamide vapour, three band systems of carbodiimide were measured and assigned to the NCN a-str mode, a combmation mode (NCN s-str -t NH a-bend) and the NH a-bending mode. The diode laser spectrum of a part of the NCN a-str band was obtained.
