Abstract

<p>Interferometric wavelength measurements have been made on thirty-three lines of the 2-0 band of CO at 4260 cm<sup>-1</sup>. These measurements were made relative to <i>R</i>(18) of this band, which had previously been measured against the Hg<sup>198</sup> green line, and have a relative accuracy of I part in 10<sup>7</sup>. The R(6) line of the 3-0 band has also been measured interferometrically. These data, when combined with results of other investigators, give the following values for constants, all in cm<sup>-1</sup>: <i>B</i><sub>0</sub>= 1.922521+0.0000035 <i>D</i><sub>0</sub>= 6.117×10<sup>-6</sup>+0.01×10<sup>-6</sup><i>D</i><sub>2</sub>-<i>D</i><sub>0</sub>= -0.035008 <i>D</i><sub>2</sub>-<i>D</i><sub>0</sub>= -1.9×10<sup>-9</sup><i>B</i><sub>6</sub>= 1.931285 α<sub>e</sub>= 0.017535 γ<sub>e</sub>= 1.01×10<sup>-5</sup> β<sub>e</sub>= -1.0×10<sup>-9</sup> ω<sub>e</sub>= 2169.829 <i>x</i><sub>e</sub>ω<sub>e</sub>= 13.295 <i>y</i><sub>e</sub>ω<sub>e</sub>= 0.0115.</p><p>The precise constants allow wavelengths to be calculated for the 1-0 band at 2143 cm<sup>-1</sup>. Since accurate measurements in this region are difficult to make, it is felt that these calculated values are more accurate than any measured values so far reported.</p><p>The value of <i>B</i><sub>0</sub>, when combined with recent microwave results, gives for the velocity of light <i>c</i>=299 793.7± km/sec.</p>
