ABSTRACT
Senyawa golongan kuinazolinon memiliki aktivitas biologis yang luas. Salah satunya adalah senyawa 2-[(E)-2-feniletenil]-3,4-dihidrokuinazolin-4-on yang memiliki aktifitas antibakteri. Aktivitas antibakteri paling efektif ditunjukkan oleh turunan senyawa kuinazolinon dengan cincin benzena yang tidak tersubstitusi atau tersubstitusi oleh substituen kecil dan cincin pirimidin yang tersubstitusi oleh substituen besar. Dalam rangka memperoleh senyawa turunan...

ABSTRACT
Many alkali halides crystal develop new absorption bands upon exposure to ionizing radiations. the absorbing centers responsible for these bands are called "Color-Centers". De Boer 1937 was proposed a model for one of the color centers, is called the "F-Center" which consisted essentially of an electron trapped at the position...
