이번 실험은 spectrofluorometer를 이용하여 250nm, 350nm에서 빛을 흡수하고 450nm에서 fluorescence를 방출하는 quinine에 대한 spectrum을 얻어 fluorescence spectroscopy로 unknown quinine의 농도를 결정하고, 특정 조건에 따른 quinine의 quenching을 확인해 보는 데에 목적이 있다. 농도 결정 실험에서 solvent가 0.05M H2SO4(aq)인 quinine sta

coffee from an Einstein coffee mug. He peers at a
complex computer rendered molecule displayed on his
screen. He pecks a few keys and the molecule shifts

The scene has a dream-like, choreographed quality.

The carnivores jaws are bigger than the boys head.
The boy smiles at him. Pulls a piece of raw meat out of
