It is shown that the OH 1720-MHz line can be strongly inverted by collisions which excite the rotation states, preferentially the $sup 2$$pi$$sub 3$/$sub 2$ ladder. It is also argued that radiative pumps (of any wavelength) can strongly invert only the 1612-MHz line. Inversion of the 1720-MHz line with vertical-bartauvertical-barapproximately-less-than1 can be achieved by either collisional or radiative pumps at low OH densities (n/sub OH/10$sup -3$-10$sup - 4$ cm$sup -3$).
