The partnership Anywhere between Uv-VIS Assimilation and you will Construction of Normal Compounds
There are numerous colored normal substances, particularly dyes and you can pigments. Exactly how will it be these particular tone occur? Discover a virtually relationship between the color of a natural substance and its particular construction. Here, I could determine thisrelationship playing with intake spectra out of organic compounds acquired that have Shimadzu’s Ultraviolet-2550 Uv-VIS spectrophotometer.
step one. The relationship Between Conjugated Double bond Options and you will Intake Highs
There are many organic substances that have conjugated double-bond systems (hereafter referred to as “conjugated assistance”), where some other thread is actually a double bond. This type of conjugated systems has a large influence on level wavelengths and you will intake intensities. Fig. step 1 reveals the newest formations out of benzene, naphthalene, and anthracene. Fig. 2 reveals brand new assimilation spectra acquired because of the dissolving these types of compounds in the ethanol and viewing the fresh resulting solutions. （更多…）
