We report the observation of high resolution (0.008 cm⁻¹) infrared absorption spectra of CO₂ molecules isolated in solid parahydrogen(pH₂) matrices at T=2.4 to 4.8 K. Several extremely sharp (0.01 to 0.04 cm⁻¹ full-width-at-half-maximum) absorption features appear in the 2343.5 to 2345 cm⁻¹ region....
