Determining the composition of cometary nuclei is key to understanding the formation of our Solar System. In recent years, excellent progress has been made towards grouping comets into an emerging taxonomy based on their parent volatile abundances, largely through quantitative measurements at infrared and millimeter wavelengths. In this work, we analyzed high-resolution infrared spectra of comet C/2000 WM1 (LINEAR), observed on 25 Nov. 2001, with the Near InfraRed SPECtrograph (NIRSPEC) on the Keck II telescope. We detected multiple parent species: H2O, HCN, CH4, C2H2, C2H6, H2CO, CH3OH, whose production rates, rotational temperatures, and mixing ratios will be presented. Our results demonstrate that WM1 is depleted in its organic chemistry, compared to the "organics-normal" group identified in a previously analyzed sample of Oort cloud comets.
