Abstract: 本論文利用低溫間質隔離技術搭配霍氏轉換紅外光譜儀(FTIR)研究NH3在Ar間質和para-H2(p-H2)間質中500-5000 cm-1光區的紅外吸收光譜。在Ar間質中首度觀測到ν1和ν3振動模除aR(0,0)和arR(0,0)外之轉動譜線,及泛頻2ν2之吸收譜線。由ν2和ν4振動模之譜線強度隨時間的變化,測得核自旋衰減速率約為0.100 h-1。藉極化差異光譜指認間質造成J=1分裂成M=0和±1能階之平均分裂大小為1.3 cm-1。在p-H2間質中成功觀測到ν1、ν3和ν4振動模的轉動譜線,且在ν2和ν4光區中各有一強度隨沉積步驟結束即迅速減弱之譜線,推論為孤立的NH3吸收譜線。由各振動模的譜線測得核自旋衰減速率介於0.056-0.098 h-1之間。藉極化差異光譜指認間質造成J=1能階之分裂小於0.5 cm-1。
