Phase of particles on a stationary wave

[DarkStalker]

Are the particles on either side of a node 180 out of phase?
Let's say there's a stationary wave, and X and Y are two points on either side of a node, moving in opposite directions. Are X and Y 180 degrees out of phase with each other?

Yes particles within a node vibrate in one phase (only their amplitude is changing with x) and across a node the string inverts (a phase change of 180 degrees) so I should think yes.
