31. As a result, spectral lines may shift or split. 32. This was the case with his work on the intensity of Zeeman effect spectral lines . 33. It could only predict the spectral lines of hydrogen; it couldn't predict those of multielectron atoms. 34. A spectrometer is used in spectroscopy for producing spectral lines and measuring their wavelengths and intensities. 35. This spectral line broadening has many different causes. 36. Quasar redshifts are measured from the strong spectral lines that dominate their visible and ultraviolet spectra. 37. His doctoral thesis dealt with the effects of Zeeman effect on spectral lines of noble gases. 38. Their statistics are broadening of spectral lines . 39. Spectral lines of the diffuse series are split into three lines in what is called fine structure.40. This spectrum is made of hundreds of thousands of sharp spectral lines with a constant frequency interval.
