His early research (1970-1980) has focused on energy transfer processes in molecular systems.

"I think this is likely to be a very common theme in how complex molecular systems evolved," he said.

This property is not common among other molecular systems.

A molecular system in the real world is unlikely to be present in vacuum.

The Hamiltonian of a molecular system may be taken as:

Replicating cells show that molecular systems can assemble every system found in a cell.

The researchers also considered a real molecular system and found that their calculations predict its conductivity pretty well.

He suggested that both morphological and molecular systems be used in future classification schemes.

Stable states of molecular systems correspond to global and local minima on their potential energy surface.

However, such construction requires detailed knowledge of a molecular system and introduces significant arbitrariness.
