We have undertaken a comprehensive search for the first excited state of OH emission (J=5/2, 2?3/2) in Planetary and Proto- Planetary Nebulae. With the Effelsberg telescope, we confirm the detection of Vy 2?2 and we present one new detection in the pPN K3?35. This detection has been confirmed by subsequent observations made at 6035 MHz with the MERLIN interferometer. This is the first detection of 6 GHz OH maser emission from a post-AGB star.Read less <
