Abstract

화학 반응은 원자나 분자가 서로 작용하여 결합이 분해되거나 생성되는 동적인 과정이다. 일반적으로 이러한 동적인 과정은 매우 빠른 시간 내에 일어나기 때문에 (보통수 펨토초에서 수 피코초 내에 일어난다) 화학 반응 도중에 나타나는 중간체(transient structure)의 구조 변화나 분자의 움직임을 실시간으로 잡기 위해서는 매우 높은 시간 분해능이 필요하다. 이러한 중간체의 구조 동역학(structural dynamics)은 그 대상이 되는 분자의 화학적/생물적 기능에 매우 중요한 정보를 제공하기 때문에 실시간 분자 동역학 연구는 복잡한 화학적/생물적 시스템의 메커니즘 규명 연구에 필수적이라고 할 수 있다.
