摘要

We present accurate new wavenumbers for a set of 13 mid-infrared fine-structure lines. The wavenumbers were determined from observations of the planetary nebula NGC 7027 and of the red supergiant a Scorpii. Most of the new wavenumbers are good to within 0.0025%, or 8 km s~(-1). We provide details on the measurements and present an analysis of the errors. In addition, we present the first observations of hyperfine splitting in the [Na IV] 1106 cm~(-1) line.
