 The authors used the IRAM 30 m telescope to search for four transitions between 102 and 169  GHz. Three lower energy transitions were detected, the higher lying transition near 102 GHz was within the noise level, in agreement with a rotational temperature of about 10 K. The authors used the IRAM 30 m telescope to search for four transitions between 102 and 169  GHz.
