· Astrophys. J.; (United States)
Infrared observations of (Ne II), (S IV), and (Ar III) are used with optical observations to discuss the abundances of Ne, S, and Ar in 18 planetary nebulae. In addition, infrared observations of 18 other nebulae are presented. The derived abundances of S and Ar are each slightly enhanced relative to previous studies.
