Description

Intermediate (lambda/Δlambda approx.= to 400) and low (lambda/Δlambda approx.= to 100) resolution spectra of IRS7 from 3.0-3.6 μm are presented. Sharp absorption features previously reported at 3.192 and 3.295 μm are not confirmed. The overall broad absorption characteristics and the presence of a shallow feature in the red wing of the broad 3.4 μm absorption are confirmed. This shallow feature is resolved, approx. 0.036 μm wide with an equivalent width of 30 +- 10 A and centred at 3.489 +- 0.005 μm. (author)
