Scientific paper

Detections have been made of the interstellar 13CH+ satellite lines of λ4232 in high-resolution spectra of 20 Tau, ξ Per, and ζ Oph and of λ3957 in ζ Oph that were taken using a Reticon detector. These detections lead to 12CH+/113CH+ abundance ratios of 49( + 12, -8), 59( +24, - 13), and 77( + 17, -12) for the 20 Tau, ξ Per, and ζ Oph clouds, respectively.
