Definition

1. Noun (Chemistry):
   • Photolysis: A chemical decomposition reaction caused by the absorption of light or other electromagnetic radiation. The process involves the breaking of chemical bonds in a molecule by photons.

Usage Examples

• Noun:
  • Quang phân là một quá trình quan trọng trong hóa học khí quyển. (Photolysis is an important process in atmospheric chemistry.)
  • Sự quang phân của ozone có thể tạo ra oxy nguyên tử. (The photolysis of ozone can produce atomic oxygen.)

Advanced Usage

• "quang phân học" (photochemistry): The branch of chemistry concerned with the chemical effects of light, which includes the study of photolysis.
  • Quang phân học nghiên cứu các phản ứng như quang phân. (Photochemistry studies reactions such as photolysis.)

Variants and Related Words

• Sự quang phân (n): The process of photolysis.

  • Sự quang phân của nước tạo ra hydro. (The photolysis of water produces hydrogen.)

• Phân hủy quang học (n): Photodegradation; a more general term for light-induced breakdown, often of polymers or materials.

  • Phân hủy quang học có thể làm hỏng nhựa. (Photodegradation can damage plastic.)

Synonyms

• Photodissociation: A specific type of photolysis where a molecule is broken into smaller fragments by light.
• Light-induced decomposition: A descriptive synonym for the process.

Related Scientific Concepts

• Quang hợp (Photosynthesis): A biological process that uses light energy, distinct from but sometimes conceptually linked to photolysis in educational contexts.

  • Quang hợp liên quan đến các phản ứng phụ thuộc ánh sáng, không phải là quang phân. (Photosynthesis involves light-dependent reactions, it is not photolysis.)

• Phản ứng quang hóa (Photochemical reaction): Any chemical reaction initiated by light absorption. Photolysis is a primary example.

  • Quang phân là một loại phản ứng quang hóa. (Photolysis is a type of photochemical reaction.)
