2.6.1 Spektroskopi UltraViolet
Spektroskopi ultra violet merupakan suatu teknik analisis yang berdasarkan atas pengukuran serapan suatu larutan yang dilalui radiasi monokromatis ultra violet. Serapan molekul di daerah ultra violet bergantung kepada struktur elektronik dari molekul dan penyerapan sejumlah energi akan menyebabkan elektron pada tingkat dasar tereksitasi ke orbital yang lebih tinggi. Sinar Ultraviolet tidak dapat dideteksi oleh mata kita, sehingga senyawa yang dapat menyerap sinar ini merupakan senyawa yang tidak memiliki warna, bening dan transparan. Untuk sampel keruh harus dibuat jernih dengan filtrasi atau centrifugasi. Spektroskopi ultra violet memberikan informasi ikatan rangkap atau konyugasi aromatik dalam suatu molekul dan adanya atom yang memiliki pasangan elektron bebas (Silverstein et al.,1981).

2.6.1 UltraViolet SpectroscopyUltra violet spectroscopy is an analytical technique that is based on the measurement of the absorption of a solution where monokromatis ultra violet radiation. Molecular absorption in the ultraviolet region is tied to the electronic structure of molecules and the absorption amounts of energy will cause the electrons excited at a basic level to a higher orbital. Ultraviolet light cannot be detected by our eyes, so a compound that can absorb these rays are compounds that have no color, clear and transparent. For the sample should be made crystal clear to murky with filtration or centrifugasi. Ultra violet spectroscopy provides information double bonds or an aromatic molecule conjugations and the existence of atoms with free electron pairs (Silverstein et al.,,1981).

2.6.1 Spectroscopy UltraViolet
UV spectroscopy is an analytical technique that is based on the measurement of absorbance of a solution through which the monochromatic ultraviolet radiation. Uptake of molecules in the ultraviolet region depends on the electronic structure of molecules and absorption of a number of energy will cause the excited electron at a basic level to a higher orbital. Ultraviolet rays can not be detected by our eyes, so that compounds that can absorb these rays is a compound that has no color, translucent and transparent. For turbid samples should be made ​​clear by filtration or centrifugasi. UV spectroscopy gives information or conjugated aromatic double bond in a molecule and the existence of atoms that have a lone pair (Silverstein et al., 1981).
