柠檬的清香可以用英语表示为 "lemony scent" 或 "citrusy scent".
柠檬的清香来源于柠檬中含有的挥发性油脂。柠檬油中含有柠檬酸、香茅醇、芳樟醇、芳樟醛等化学成分，这些化学成分在空气中蒸发，形成了柠檬的清新清香。
一些英文例句和中文翻译如下：
The room was filled with the lemony scent of freshly squeezed lemon juice. (房间中弥漫着新鲜榨出的柠檬汁的柠檬清香。)
The citrusy scent of the lemon tree wafted through the open window. (柠檬树的柠檬清香从敞开的窗户中飘过来。)
She sprayed the lemony scent of the air freshener to mask the smell of cigarette smoke. (她喷洒了柠檬香味的空气清新剂，以掩盖烟草的味道。)
