It really would happen even if we did not know the experimental data.
That view also does not agree with the experimental data.
Sure, they got the details all wrong, and worked without experimental data.
Some experimental data to illustrate the effect are shown in the following table.
The striking fact about these studies is the tiny amount of experimental data.
Certainly we have no experimental data to say they don't.
What can he prove with only a little math and no experimental data?
The experimental data are in good agreement with predicted values.
At the time, however, no experimental data existed to support such a hypothesis.
These results agree with the existing theoretical or experimental data.
