The low-mass star formation Lupus complex sits within the expanding HII shell of the Upper Scorpius OB cluster, with shock impacts triggering multiple star formation. IRAS 15398 in Lupus I-1 is considered as a WCCC source rich in COMs, molecular line emissions allowing distinctions between molecules particularly prevalent in either compact or extended regions. Molecular emissions from close to the protostar as well as from gas spreading in outflow material are involved. Within the latter are found distinguishable localized components (‘blobs’) that show likely shock enhanced chemistry. As is the case for IRAS 16293 and NGC 1333, disk emission is separable from envelope emission through characteristic species and levels of molecular excitation.
