摘要：

Quantum electrodynamic effects have been systematically tested in the progression of rotational quantum states in the X-1 Sigma(+)(g), v = 0 vibronic ground state of molecular hydrogen. High-precision Doppler-free spectroscopy of the EF1 Sigma(+)(g)-X-1 Sigma(+)(g) (0,0) band was performed with 0: 005 cm(-1) accuracy on rotationally hot H-2 (with rotational quantum states J up to 16). QED and relativistic contributions to rotational level energies as high as 0.13 cm(-1) are extracted, and are in perfect agreement with recent calculations of QED and high-order relativistic effects for the H-2 ground state.
