Popis: 1 H NMR spectra were obtained for silicon dioxide films that were thermally grown under clean room conditions. Bulk hydrogen in a concentration of approximately 1.2×10 198 H/cm 3 was detected in a 1.1-μm thick wet oxide grown at 1000 o C. The relatively long (∼15 s) spin-lattice relaxation time for this sample is consistent with bulk hydrogen, while a narrow 3 kHz half-width at half maximum (HWHM) Gaussian line shape suggests that the majority of hydrogen in this film is well isolated. Thinner thermal oxides, own under a variety of conditions, were exposed to the ambient to assess the effects of sample aging
