This paper has studied the phthalocyanin complex of Cobalt synthesized by benzene bitter wine-urea law,and after depuration,an infrared, ultra-violet spectrograph determination is carried.
Methods Video-stroboscopy was used to reveal the laryngeal cavity and dynamic changes of the vocal fold, and sound spectrograph was used to examine audio frequency, pitch and width.
What we are doing is, we take the light that comes from one of these bodies and then it's channeled through this instrument is called NIRSpec, and this is a near infrared spectrograph.
