Visible and infrared spectra, from two, widely separated epochs, are presented for the nova V606 Vulpeculae. The first, acquired 7 days after the nova reached maximum light, displayed emission from carbon monoxide plus a wealth of low excitation atomic lines characterisic of an Fe II-type novae early in its spectral development. The second, from 80 days later and after additional mass ejection, provided a spectral snapshot of a nova just prior to dust formation. It also was dominated by emission lines of mostly neutral atomic species, many of which included P-Cygni components. However, no spectral features from any molecules were detected, leaving in question what constituted the building blocks of the dust grains that formed shortly thereafter.
