By means of diode laser spectroscopy we observed signals of \((\mathrm{CO})_{2}\) in a supersonic jet expansion. Nineteen lines of a \(K: 2 \leftarrow 1\) transition were detected by concentration-frequency double modulation in the infrared region. This modulation technique was recently developed in
