Angular dynamics of molecular bodies

In this work, we propose a coordinate method for determining the position of molecular bodies in space that does not use either Euler angles or Hamilton quaternions.

Description
Summary:In this work, we propose a coordinate method for determining the position of molecular bodies in space that does not use either Euler angles or Hamilton quaternions. The capabilities of the developed high-precision computational algorithm are demonstrated using the example of the Louis Poinsot instability. The change in the nature of this instability when a molecular magnetically susceptible body is exposed to an external magnetic field is also analyzed.
