Colorado State University

What you'll study

The programme combines advanced coursework in physical and theoretical chemistry with hands-on laboratory experience and an independent research project or thesis. Core topics typically include quantum chemistry and molecular quantum mechanics, statistical mechanics, advanced spectroscopy (including electronic, vibrational and rotational techniques), ultrafast and nonlinear optics, and computational methods for modelling molecular structure and dynamics.

• Advanced Quantum Chemistry: post-Hartree–Fock methods, density functional theory and excited-state methods.
• Spectroscopy and Photonics: electronic and vibrational spectroscopy, laser-based techniques, time-resolved/ultrafast methods and optical instrumentation.
• Computational Chemistry and Modelling: molecular dynamics, quantum dynamics and software applications for spectroscopy simulation.
• Statistical Mechanics and Thermodynamics: foundations for interpreting experimental observables and spectroscopic line shapes.
• Laboratory and Methods Courses: advanced experimental practicum in optics, instrument design and data acquisition/analysis.
• Research Thesis or Project: independent, faculty-supervised research that applies quantum chemical theory or optical methods to a problem in physical chemistry, materials or molecular science.

Entry requirements

Applicants should hold a recognised bachelor’s degree in chemistry, physics, chemical engineering or a closely related discipline, with substantial coursework in physical chemistry and mathematics (calculus and linear algebra). Successful applicants commonly demonstrate preparation in quantum mechanics and undergraduate laboratory experience.

• Academic transcripts showing a strong record in science and mathematics courses.
• Personal statement outlining research interests and reasons for pursuing the programme.
• Two or three academic references attesting to research potential and technical ability.
• CV or résumé summarising laboratory experience, computational skills and any publications or presentations.
• International applicants may need to demonstrate English language proficiency through an accepted test.

Admission is competitive and can be strengthened by prior research experience in spectroscopy, optics, computational chemistry or related laboratory work. Prospective students are encouraged to contact faculty whose research aligns with their interests before applying.

Career prospects

Graduates from this programme are prepared for a wide range of technical and research careers. Typical pathways include continuing to PhD study, roles in national laboratories, and positions in industries that rely on optical techniques and molecular modelling.

• Academic and industrial research: physical chemistry, photophysics, quantum materials and molecular spectroscopy groups.
• Photonics and optics industry: laser systems, optical communications and measurement instrumentation.
• Semiconductor and materials companies: device characterisation, spectroscopy and materials modelling.
• Analytical and instrumentation firms: development and application of spectrometers and sensors.
• Government and national labs: research in atmospheric sciences, quantum information, precision measurement and applied spectroscopy.
