A new 4Σ − a4Π electronic transition of ScC in the near infra-red

繼先前我們在可見光區的碳化鈧自由基光譜工作(Chen et. al., J. Chem.Phys. 149, 074302-1‒074302-15(2018) ),在近紅外光譜區找到一新系統。除了得到更精準的a4Π光譜常數外,提供在星雲中或太陽裡搜索ScC自由基的資訊。

Following our previous work of ScC radical (Chen et. al., J. Chem. Phys. 149, 074302-1‒074302-15 (2018) ), a new system in the near Infra-red region was found. Improved spectroscopic constants of a4Π were obtained, the line positions of this sytem are provided for searching the ScC radical in the interstellar cloud.

碳化鈧自由基的 4-a 4Π5/2 (1,0)近紅外光譜躍遷(部分), 黑色光譜為實驗結果,紅色譜線為譜帶模擬。

The near Infra-red spectrum of the 4-a 4Π5/2 (1,0) band of ScC radical (part). The spectrum colored in black is our experimental results, and the red lines are simulated band contours with a line width of 0.1 cm-1 narrower than our experimental conditions to show the details of this rotational structure.
