We have detected CH⁺ and CH molecular absorption lines from the youngcompact planetary nebula IC 4997 from high resolution optical spectra. A high-resolution infra-red (H and K bands) spectrum provides detection of H₂ emission lines among many other lines. The H₂ lines provide an excitation temperature of 2100 K which may result from UV fluorescenc...
