본문내용

본 실험에서는 Thermal lens 효과를 이용해 용매의 열용량(C_p)과 dye의 몰 흡광도(ε)를 계산했다. He-Ne laser와 oscilloscope를 사용하여 acetone과 methanol에 각각 녹인 azulene과 malachite green oxalate의 빛 강도를 측정하고, Origin에서 exponential function fitting 후,C_p, ε을 계산했다. Azulene-Acetone 용액의 C_p=182.86J/mol⦁K(오차 45.76%), ε=0.5788M^(-1) cm^(-1)이었고, Azulene-Methanol 용액은 C_p=252.21J/mol⦁K(오차 217.24%), ε=4.66M^(-1) cm^(-1), Malachite green-Acetone 용액은 C_p=154.79J/mol
