AbstractWe report on a 95ghz (8(0)-7(1) a(+)) methanol (ch3oh) emission survey with the purple mountain observatory delingha 13.7 m telescope. eight supernova remnants (snrs) with angular size less than or similar to 10' were observed, but emission was only detected in three snrs near the galactic center (sgr a east, g 0.1-0.1 and g 359.92-0.09). ch3oh emission mainly surrounds the snrs and can be decomposed into nine spatial peaks with the velocity range of eight peaks being (-30, 70) km s(-1), and the other is (70, 120) km s(-1). they are probably excited by interaction with these snrs and adjacent molecular gas in the central molecular zone (cmz), although star formation may play an important role in exciting ch3oh emission in some regions of cmz. we infer that tidal action is unlikely to be an excitation source for ch3oh emission.
