What is the rotation matrix and R the Euler?

Hello every one, I am a new comer.

During my research of ionization rate of molecule using ADK method, I meet a question.

What is the rotation matrix and R the Euler angles between the molecular axis (in Eq. (8) of reference PHYSICAL REVIEW A, 66, 033402 (2002)) and what form is the rotation matrix?

Well the http://en.wikipedia.org/wiki/Euler_angles#Matrix_expression_for_Euler_rotations" on Euler angles has the transformation matricies right there.

Since that article seems to be about diatomics (didn't read the whole thing), I'd assume the Euler angles in question are the angle and dihedral angle between the field vector and the molecular axis.

Thank very much, I will read carefully!
