Excerpts

In EGFP, the direction of the transition dipole moment is 14° from the line connecting the centers of the aromatic rings.

In mTurquoise2, the direction of the transition dipole moment is 4° from the line connecting the centers of the aromatic rings.

In mCherry, the direction of the transition dipole moment is -8° from the line connecting the centers of the aromatic rings.
