Methanol in dense clumps of the filament WB 673
We study physical conditions in the dense clumps from the molecular filament WB 673. Using the 96 GHz series if methanol lines we obtain rotation temperatures with the population diagram method. We find that the rotation temperatures are about 2-3 times less than the gas kinetic temperature. We conclude that other methanol series are needed to study the methanol excitation in details.
