| 21. | The suffix notation indicates that absorption lines of iron and the carbon-hydrogen G-band are abnormally weak.
|
| 22. | It results in a much lower temperature of the tagged molecules, with sharper infra-red absorption lines.
|
| 23. | Radiation treatment induces characteristic sharp optical absorption lines which can be easily detected by spectroscopic techniques.
|
| 24. | If restricted to absorption lines it would look similar to the illustration ( top right ).
|
| 25. | When examined with a spectroscope a strong vanadium absorption line at 475 nm will be apparent.
|
| 26. | Ultraviolet emission and absorption lines provide the best diagnostics for the composition of the surrounding material.
|
| 27. | Have you noticed on that applet that the absorption lines are the same as the emission lines.
|
| 28. | :: The first proof was when the suns spectra was first analysed and absorption lines were seen.
|
| 29. | The red shift of the object was determined by analyzing the absorption lines in the quasar light.
|
| 30. | They may also display very complex H? profiles, typically having strong emission lines combined with absorption lines.
