| 21. | Chemists had assumed that hydroxyl in the atmosphere was created largely from water.
|
| 22. | Oxidizing species include singlet oxygen, hydroxyl, monatomic oxygen, and hydroperoxyl.
|
| 23. | This proceeds via single electron oxidation and hydroxyl radicals.
|
| 24. | Firstly, it involves protonation of the hydroxyl group.
|
| 25. | The hydroxyl group ( OH ) is the active site of many reactions.
|
| 26. | The amine-terminated polymer resins will not have any intentional hydroxyl moieties.
|
| 27. | A hydroxyl group is also installed on the adjacent carbon to yield samandarin.
|
| 28. | The 4 hydroxyl groups interact by hydrogen bonding and stabilize the cone conformation.
|
| 29. | In the process the TMS group migrated to the 2-hydroxyl group.
|
| 30. | The radiation amplified by hydroxyl masers is the radio continuum of its host.
