spectroscopical

It was only natural that precedence was given to the investigations first named, as a fruitful spectroscopical investigation of X-rays presupposed a certain knowledge of the lattice used.

It had already become clear that the X-radiation must arise in the inner parts of the atoms, and that consequently exact X-ray spectroscopical investigations form the only means for an experimental research of those parts.

This hypothesis has in fact been confirmed, inter alia by spectroscopical investigations into light sources placed in very strong magnetic fields.
