Nonradiative

/ˌnɒnˈreɪdiətɪv/

अविकिरणीय (बिना विकिरण उत्सर्जन के)

Origin & History

Formed from non- (“not”) + radiative (from Latin radius “ray”); used in physics/chemistry to describe processes without radiation emission.

non- (“नहीं/विना”) + radiative (लैटिन radius “किरण” से) से बना; भौतिकी/रसायन में उन प्रक्रियाओं के लिए प्रयुक्त जिनमें विकिरण का उत्सर्जन नहीं होता।

Definition

Describes a process, transition, or decay in which energy is not released as electromagnetic radiation (such as photons), but instead is transferred by other means (e.g., heat, collisions, phonons, internal conversion).

ऐसे प्रक्रम, संक्रमण या क्षय का वर्णन जो ऊर्जा को विद्युतचुंबकीय विकिरण (जैसे फोटॉन/प्रकाश) के रूप में नहीं छोड़ता, बल्कि अन्य तरीकों से स्थानांतरित करता है (जैसे ऊष्मा, टक्करों द्वारा, फॉनॉन, आंतरिक रूपांतरण)।
