-The identifications were made in the course of a molecular line survey of L483 at 3 mm carried out with the IRAM 30 m radio telescope. The survey samples cold material; the presence of the embedded Class 0 infrared source IRAS 18148−0440 is not visible in these data. 9 and 8 //a//-type transition frequencies with 4 ≤ //J// ≤ 7 and //K<sub>a</sub>// ≤ 1 were reported. \\
