I review recent results of mm-wave interferometric observations of molecular envelopes of young and proto planetary nebulae. Spatial resolutions of mm-wave interferometers now reach from one to a few arcseconds; together with line observations reveale very small structures in molecular envelopes of planetary nebulae. These small scale structures are probably caused by an instability of the radiation-driven, gas-dust outflow. Implications of these observations and theories are discussed.
