I can't imagine"In my way of thinking the phenomenon is a result of thermal molecular motion in the liquid environment (of the particles)." This is indeed the case. A suspended particle is constantly and randomly bombarded from all sides by molecules of the liquid. If the particle is very small, the hits it takes from one side will be stronger than the bumps from other side, causing it to jump. These small random jumps are what make up Brownian motion.

Brownian motion is the random movement of particles suspended in a fluid. It was first observed by Robert Brown in 1827.
Brownian motion is caused by the collision of particles with molecules in the surrounding fluid.
Brownian motion is important in understanding various physical and biological phenomena such as diffusion, osmosis, and the behavior of microscopic particles in a fluid.
Brownian motion is a direct result of the kinetic theory of gases, which states that particles in a gas are in constant motion and collide with each other.
Yes, Brownian motion can be observed in everyday life in the movement of smoke particles, the diffusion of perfume, and the random movement of pollen grains in water.
