The spectrum of $CO2$ in the region of its fundamental perpendicular vibration has been studied. Bands involving the $000,0110,0200,0220,1000,1110$ and $0310$ levels have been measured using a high resolution vacuum prism echelle spectrometer capable of resolving $.08cm-1$ and of an accuracy of absolute wavelenght measurement of $.005cm-1$. These studies yield values of various molecular constants including band origins, $\Delta B$ values, $g22,q0110,\alpha 1,\alpha 2$ and $k122$.
