We report 1.2-18.5 μm spectrophotometric measurements of the CO nova V705 Cassiopeiae (Nova Cas 1993). Observations were made over a 2.5 yr period between 7.1 and 929.4 days past outburst. This time frame was marked by all major phases of nova evolution. An optically thick, carbon dust shell formed by day 70.9. Later evolutionary stages of the dust shell are modeled using a combination of emission from carbon, silicate, and hydrocarbon grains. Using this model, we estimate carbon, silicate, and gas abundances in addition to several other calculable physical parameters.
