Spontaneous Raman scattering is inherently weak. Coherent anti-Stokes Raman spectroscopy (CARS) and stimulated Raman gain spectroscopy (SRGS) use intense laser fields to enhance signals. These methods probe vibrational and rotational transitions without requiring infrared absorption.
However, I cannot produce or link to copyrighted PDFs of commercial textbooks, nor can I assume that a PDF with that exact title is legally available for free. What I can do is write a detailed, informative article about the of atomic and molecular spectra, with a special focus on laser-based spectroscopy techniques — which is likely the subject matter of the book you’re referring to.
The book covers the following topics:
The keyword points to a specific and widely referenced textbook in the field. The book, authored by Raj Kumar (often referred to as "Rajkumar" in online searches), is a standard text for undergraduate and postgraduate students at many Indian universities.

: Use the book’s diagrams to visualize electron spin and the vector atom model, which can be difficult to grasp through text alone. Where to Find It
Atomic and molecular spectra, once decoded with prism spectrographs and photographic plates, now find their most powerful expression in laser-based experiments. From deciphering the breathing of distant planets to watching electrons dance inside a molecule, the marriage of lasers and spectroscopy continues to expand the frontiers of science. Whether you are reading Rajkumar’s textbook or building your first tunable laser spectrometer, remember that every spectral line is a fingerprint of nature’s quantum choreography — and lasers are the brightest flashlights we have to illuminate it.
These properties have given rise to powerful techniques like and other laser-based spectroscopies, which are used for everything from analyzing industrial gases to exploring chemical bond-breaking events. The synergy between atomic and molecular physics and laser technology is so profound that many modern textbooks, including Rajkumar's, treat them as inherently linked subjects.

Moving from single atoms to molecules introduces rotational and vibrational degrees of freedom. The text covers:
At the university archive, between yellowed records and a humming copy machine, he found a note dated with that strange hour: “56. Turn the lamp. Wait. Listen.” Beneath it, a recording on an old cassette had been digitized and attached: a voice that was cracked with distance and joy counting pulses, someone whispering to a child, teaching them how to divide light into its smallest truths. In the static, a laugh: “Do you hear it? The world is singing how it is made.” He played it again until the words stitched to new meaning: songs hidden in spectra.
