摘要：
The rotational spectrum of linear C3H+ has been revisited in the millimeter-wave region using a cryogenic ion trap apparatus employing a double-resonance scheme based on leak-out action spectroscopy (LOS). Eight rotational transitions (J ' F J ''= 4 F 3 up to J ' F J ''= 11 F 10) have been measured in the 85-250 GHz frequency range. With the laboratory measurements reported here, improved values for the ground-state spectroscopic constants of C3H+ have been obtained.
