Although COMs have been extensively studied in the gas phase toward protostars, their counterparts in ices, where they are thought to form at earlier stages, remain far less constrained. A number of diagnostic features of complex ices lie between 6.8 and 8.8 um, a region known as the \"COM ice fingerprint range,\" but previous infrared facilities lacked the sensitivity and spectral resolution required to quantify the weak bands therein.
