We present infrared spectroscopy from two epochs of V1533 Scorpii (=Nova Scorpii 2013); one from immediately before dust formation and a second, from one month later when dust formation was complete. The pre-dust spectrum shows strong lines of C i, features that weakened considerably but were still present after dust formation. Also present in the post-formation spectrum was O i emission from the neutral region, indicating that dust formation did not full deplete either carbon or oxygen. While thermal emission from the dust, of a temperature very close to 870 K, dominated the later spectrum, the extinction did not change measurably between epochs, indicating that little or no dust blocked the line-of-sight. Although carbon monoxide was not detected in the first epoch spectrum, weak emission from molecular hydrogen may have been present.

我们展示了来自 V1533 Scorpii（=Nova Scorpii 2013）两个时期的红外光谱；一个是在粉尘形成之前，第二个是一个月后粉尘形成完成时。尘埃前的光谱显示出强烈的 C i线，这些特征明显减弱，但在尘埃形成后仍然存在。形成后光谱中还存在 O i来自中性区域的排放，表明尘埃的形成并未完全耗尽碳或氧。虽然温度非常接近 870 K 的尘埃发出的热辐射在后来的光谱中占主导地位，但消光在不同时期之间没有可测量的变化，这表明几乎没有或没有尘埃阻挡了视线。虽然在第一个纪元光谱中没有检测到一氧化碳，但可能存在分子氢的微弱发射。
