La présence du radical hydroxyle est fondamentale dans le phénomène d’effet de serre. Ce radical constitue un puits très important pour le monoxyde de carbone et le méthane. Il nettoie littéralement l'atmosphère de plusieurs gaz à effet radiatif. Sa disparition aurait pour conséquence des augmentations marquées de la concentration des gaz à effet de serre. 8, record 1, French, - hydroxyle

hydrurooxygène(·) : prononcé «hydrurooxygène point»; forme recommandée par l’UICPA (Union internationale de chimie pure et appliquée). 2, record 1, French, - hydroxyle
Record number: 1, Textual support number: 4 OBS
radical HO· : nom descriptif. Les points sont en exposant HO· lorsque le nom du radical se termine par «yle», par exemple «hydroxyle». Ce sont des points centrés entre parenthèses après les noms qui n’ont pas le suffixe «-yle». Par exemple : hydruroxygène(·) ou HO(·). 2, record 1, French, - hydroxyle
Record number: 1, Textual support number: 5 OBS
