Some physicists, particularly French and German physicists were initially sceptical of the authenticity of the discovery. Georg Joos at the Friedrich Schiller University of Jena asked Arnold Sommerfeld at the University of Munich, "Do you think that Ramans work on the optical Compton effect in liquids is reliable?... The sharpness of the scattered lines in liquids seems doubtful to me". Sommerfeld then tried to reproduce the experiment, but failed. On 20 June 1928, Peter Pringsheim at the University of Berlin was able to reproduce Ramans results successfully. He was the first to coin the terms Ramaneffekt and Linien des Ramaneffekts in his articles published the following months. Use of the English versions, "Raman effect" and "Raman lines" immediately followed.
In addition to being a new phenomenon itself, the Raman effect was one of the earliest proofs of the quantum nature of light. Robert W. Wood at the Johns Hopkins University was the first American to confirm the Raman effect in the early 1929. He made a series of experimental verification, after which he commented, saying, "It appears to me that this very beautiful discovery which resulted from Raman's long and patient study of the phenomenon of light scattering is one of the most convincing proofs of the quantum theory". The field of Raman spectroscopy came to be based on this phenomenon, and Ernest Rutherford, President of the Royal Society, referred to it in his presentation of the Hughes Medal to Raman in 1930 as "among the best three or four discoveries in experimental physics in the last decade".
Raman was confident that he would win the Nobel Prize in Physics as well but was disappointed when the Nobel Prize went to Owen Richardson in 1928 and to Louis de Broglie in 1929. He was so confident of winning the prize in 1930 that he booked tickets in July, even though the awards were to be announced in November. He would scan each day's newspaper for announcement of the prize, tossing it away if it did not carry the news. He did eventually win that year.
