vibration frequency and bond length for H35Cl‚ H37Cl‚ D35Cl‚ and D37Cl and to compare the isotope effects to theoretically predicted values. Introduction Vibration spectroscopy is one of the most important tools for the accurate determination of molecular structure. Vibration spectroscopy also plays an important role in environmental chemistry. For example‚ the albedo of the earth’s atmosphere is controlled by the absorption of infra-red light by green house gasses‚ which include CO2‚ H2O‚ and CH4

Magnetic Resonance Imaging (MRI) is a medical imaging technology that uses strong magnetic fields and radio waves to create graphic images of the body’s anatomical and internal structures (1). MRI relies primarily on the protons in fat and water molecules of the body‚ as these protons respond to the static magnetic field created in ways that allows for a high quality image to be generated (2). These images contrasts specific tissue and different anatomical structures. For example‚ MRI can reveal

tomography (CT) scans‚ mammograms‚ ultrasounds and magnetic resonance imaging (MRI) scans. A radiologist might operate the machinery used to collect these images‚ though this task is often delegated to radiology technologists. Radiologists also occasionally monitor imaging sessions run by radiologist technologists and technicians. The specific duty of a radiologist is to diagnose an treatment of diseases and injuries using imaging. A radiologist work 8 to 10 hours a day and 40 to 50 hours a week and

Radiologist. A radiologist uses medical imaging technologies to diagnose and sometimes treat diseases. Originally it was the aspect of medical science dealing with the medical use of X-rays emitted by X-ray machines or other such radiation devices for the purpose of obtaining visual information as part of medical imaging. Due to the extensive training radiologists traditionally receive in medical image interpretation‚ radiologists now also direct other imaging technologies (such as ultrasound‚ computed
