Further infrared studies of the pre-main-sequence object HD 97048

8 to 13 μm spectrophotometry of HD 97048 has been obtained, following the discovery of a new narrow emission feature at 3.5 μm by Blades and Whittet. The spectrum shows the familiar but unidentified emission feature at 11.25 μm superimposed on a hot grey continuum. The failure to detect other emission structure in this window rules out polyoxymethylene as the source of the 3.5 μm feature. The relationship with the associated reflection nebula is discussed.
