Scientific paper

Spectroscopic λ3883 CN band strength measurements are presented for bright giants in the globular cluster NGC 362. A bimodal cyanogen distribution appears to be present, with a predominance of CN-rich stars. The results are consistent with previous surveys of the λ4216 CN band among the bright giants, and the λ3883 CN band among the subgiants. An anticorrelation exists between the λ3883 CN band strength and the infrared CO color. The behavior of CN versus CO in NGC 362 is compared with that seen in other globular clusters.
