Russian Translation(s) & Details for 'photodissociation'

English Word: photodissociation

Key Russian Translations:

• фотодиссоциация [fɐ.tə.dʲɪ.səˈt͡sɨ.ə] - [Formal, Scientific]

Frequency: Low (Primarily used in scientific and academic contexts; not common in everyday conversation)

Difficulty: Advanced (C1 or higher, as it involves specialized scientific terminology and requires knowledge of chemistry and Russian technical language)

Pronunciation (Russian):

фотодиссоциация: [fɐ.tə.dʲɪ.səˈt͡sɨ.ə]

Note on фотодиссоциация: The stress falls on the fourth syllable ("t͡sɨ"), which is a common challenge for English speakers due to the soft consonants (e.g., 'дʲ' as in 'дь'). Pronunciation may vary slightly in fast speech.

Audio: []

Meanings and Usage:

Meaning: The process by which a chemical compound is broken down by the absorption of light, often in photochemical reactions.

Translation(s) & Context:

• фотодиссоциация - Used in formal scientific, chemical, or astrophysical contexts, such as describing molecular breakdown in sunlight.

Usage Examples:

• В процессе фотодиссоциации молекулы воды распадаются на водород и кислород под действием ультрафиолетового излучения.

  In the process of photodissociation, water molecules break down into hydrogen and oxygen under ultraviolet radiation.

• Фотодиссоциация озона в стратосфере способствует образованию озоновой дыры.

  Photodissociation of ozone in the stratosphere contributes to the formation of the ozone hole.

• Учёные изучают фотодиссоциацию органических соединений для разработки новых солнечных батарей.

  Scientists are studying the photodissociation of organic compounds to develop new solar batteries.

• Фотодиссоциация может происходить в космосе, где звёздный свет вызывает разложение межзвёздных молекул.

  Photodissociation can occur in space, where starlight causes the breakdown of interstellar molecules.

• В лабораторных условиях фотодиссоциация используется для анализа химических реакций на молекулярном уровне.

  In laboratory conditions, photodissociation is used to analyze chemical reactions at the molecular level.

Russian Forms/Inflections:

фотодиссоциация is a feminine noun (from Greek/Latin roots) and follows standard Russian noun declension patterns for third-declension nouns. It is not commonly inflected in everyday use but changes in scientific writing based on grammatical case and number.

Note: This word is relatively stable and does not have irregular forms, but always check context for precise usage in scientific texts.

Russian Synonyms/Antonyms:

• Synonyms:
  • светораспад (svetoraspad) - Similar, but more general, often used interchangeably in basic contexts.
  • фотолиз (fotoliz) - Exact synonym, emphasizing the photolytic aspect.
• Antonyms:
  • синтез (sintez) - General opposite, meaning synthesis or combination, not specific to light processes.

Related Phrases:

• процесс фотодиссоциации - Process of photodissociation; used in descriptions of chemical reactions.
• фотодиссоциация молекул - Photodissociation of molecules; common in astrophysics contexts.
• индуцированная фотодиссоциация - Induced photodissociation; refers to artificially triggered processes in labs.

Usage Notes:

This term directly corresponds to "photodissociation" in English and is used exclusively in scientific or technical contexts, such as chemistry, physics, and environmental science. It is formal and not suitable for casual conversation. When choosing between synonyms like "фотолиз," opt for "фотодиссоциация" in detailed academic writing for precision. Grammatically, it requires agreement with feminine nouns in Russian sentences.

• Always pair it with appropriate prepositions, e.g., "в процессе" (in the process of).
• In translations, ensure the context specifies the light-induced aspect to avoid confusion with other types of dissociation.

Common Errors:

English learners often confuse "фотодиссоциация" with "диссоциация" (dissociation without specifying light), leading to inaccurate descriptions. For example:

• Error: Использовать "диссоциация" вместо "фотодиссоциация" в контексте световых реакций. (Using "dissociation" instead of "photodissociation" in light-related contexts.)
• Correct: Фотодиссоциация происходит под действием света. (Photodissociation occurs under the influence of light.)
• Explanation: The prefix "фото-" is crucial to indicate light involvement; omitting it changes the meaning entirely.

Cultural Notes:

As a scientific term, "фотодиссоциация" does not carry significant cultural connotations but reflects Russia's strong tradition in chemistry and space research, influenced by pioneers like Dmitri Mendeleev. It is commonly discussed in educational contexts related to environmental issues, such as ozone depletion, which has global relevance.
